A supplemental braking system is a must when towing a car or truck behind your RV. Without it, the weight of the towed car can create a safety hazard, strain your RV's brakes, or affect your RV's warranty. Most states require a supplemental braking system.


Automatic, Proportional Braking

There are many supplemental braking systems available to RV owners who choose to tow a car. Stay-IN-Play DUO combines the best features into a single system that is both automatic and fully proportional. This system relies not only on your towed car's momentum to activate, but also on your RV's brake light signal. As a result, the DUO will automatically activate any time you engage your RV's brakes, so long as there is enough deceleration for the system to detect. And when it does activate, your towed car's brakes will engage with an intensity that matches the slowing or stopping action of your RV.


An inertia-sensing mercury switch inside the DUO's controller is what makes this system proportional. This switch reads and interprets changes in forward momentum that occur when your towing setup decelerates. As your RV and car slow down, this switch sends a signal to activate your towed vehicle's brake pedal with an intensity that matches the deceleration of your RV. The result is even braking across your towing setup. Whether you lightly tap the brakes in your RV or apply them hard in a panic situation, your towed car's brakes will be applied proportionately.


Dual Activation Signals

G Force Controller

The G-Force controller is responsible for sending the signal that activates the brakes in your towed car. When the coach brake lights come on, the tow bar wiring sends a signal to this controller. This signal powers the internal, inertia-sensing mercury switch, enabling it to detect deceleration. If a change in forward momentum is detected, the G-Force controller initiates the braking process by sending an activation signal to the system's operating unit.


If the mercury switch is powered but there is no change in momentum, the system will not activate the towed car's brakes. Likewise, if a decrease in forward momentum occurs but there is no brake light signal from the RV, the inertia sensor will not be able to register the deceleration, and the system will not activate the towed car's brakes.


Because the DUO will not work without your RV brakes being applied, there is no false braking. When you downshift in your RV without applying the brakes, the DUO will not mistakenly depress your towed car's brake pedal because that first activation signal is not there. And because there is no time delay, this proportional system delivers instant braking in an emergency.


Note: The G-Force controller mounts in the towed car and must be pointed it in the direction of travel - with the toggle switch facing the rear of your vehicle - for the internal sensor to function properly.


Sensitivity Adjustment

You can adjust the sensitivity of the inertia-sensing mercury switch with a knob on the front of the G-Force controller. Adjusting the sensitivity lets you decide how intense the change in momentum must be for the sensor to respond. Adjust it to fit your personal preference so that you can get a customized braking experience. Set the sensitivity low and the DUO will only respond when you forcibly step on your RV's brake pedal. Set the sensitivity high and it will respond when you merely tap your RV's brakes.


To fine-tune the sensitivity, first move the knob all the way to its most sensitive setting. From there, you can apply the coach brakes and gradually move the knob until you get the setting right where you want it. You only need to set the sensitivity upon initial setup.


Permanent Installation with Concealed Components

Operating Unit

The operating unit receives the signal from the G-Force controller to activate. It then delivers air through a hose to the actuating cylinder, which depresses the towed car's brake pedal with a pressure that ensures your car will brake in proportion to the deceleration of your RV.


DUO Under Hood

Once you install the Stay-IN-Play DUO's operating unit under the hood of your towed vehicle, it stays concealed. Not only will it be installed and ready for the next time you want to tow your car, but it will also be out of the way so that you won't notice it when you drive your car normally. In addition, there is no need to constantly set up or remove this system. As a result, you don't need to worry about where to store the components when you're not towing.


Actuating Cylinder

Small Cylinder

The actuating cylinder depresses your towed car's brake pedal upon receiving air from the operating unit. This small cylinder stays mounted on the arm of your towed car's brake pedal at all times and will not interfere with braking while driving.


Actuator on Pedal

Mount this cylinder so that it is perpendicular to the firewall when you depress the brake pedal. A clamp anchors the actuator to the firewall.


To connect the actuating cylinder to the operating unit, you will need to run the included air hose through your towed car's firewall. You can usually create the necessary, small opening without drilling. In most instances, you can cut a slit in the hood release cable grommet. Simply cut the end of the air line at an angle to poke it through the slit.


Vacuum Pressure Creates Smooth Braking

Normally, when you activate the brakes in your vehicle, a vacuum multiplies the pressure you apply to your brake pedal, creating the force necessary to stop the full weight of the moving car. On most cars and trucks, this vacuum-assist function does not work when the engine is off. As a result, many supplemental braking systems on the market have to use an excessive amount of pressure to effectively depress the towed car's brake pedal.


The Stay-IN-Play DUO's operating unit ties into your car's vacuum line and uses a built-in vacuum pump to activate the vacuum-assist function of your car's brakes when it's being towed. As a result, the actuating cylinder of the Stay-IN-Play DUO does not need to apply extreme force to the brake pedal to achieve proper braking. The Stay-IN-Play DUO will replenish your towed car's vacuum after each braking event so that you will get smooth, even braking every time.


Built-In Safety Features

Most supplemental braking systems have methods of letting you know you when the system itself is activated, regardless of whether the towed car's brake pedal is depressed. Such setups leave opportunities for false notification. The Stay-IN-Play DUO's system is different. This system's LED monitor connects to your towed car's brake light switch. When your car's brake light goes on or off, so does the notification light. So you can tell whether your car's brake pedal is depressed.


You can install the monitor light on your RV's dash, or you can save time by attaching the monitor light to the back of the rearview mirror of the towed vehicle. This way you can see the light from your RV's backup camera or rearview mirror. The system includes the necessary parts for either installation method.


Note: If the towed car's brake lights do not illuminate when its engine is off, then a stop light switch kit (sold separately) is required for proper notification.


The breakaway system ensures that your car will come safely to a stop if it accidentally detaches from the RV while you are towing. A switch mounts to the front of the towed vehicle. This switch - which is wired into the operating unit - includes a pin that connects to your RV's hitch receiver with a breakaway cable. If the car separates, the cable pulls the pin from the switch, causing a signal to be sent to the operating unit.

Video Transcript for SMI Stay-IN-Play DUO Braking System Review

Today we're going to be taking a look at the SMI Stay In Play Duo Supplemental Braking System, part number SM99251. This is an automatic proportional braking system that never has to be removed, replaced, or reset. The duo will activate when the RV or tow vehicle brakes are on. There's a switch in the car that detects braking. With the sensitivity controlinertia sensor set inside the vehicle, you can adjust more or less braking, depending on the weight of the vehicle. Let's go over our components for the Stay in Play duo system.

This is the control unit. It also has a vacuum pump built inside. The control unit, we get wired to the break-away switch in the operating unit. The long, black hose that comes out of it is for vacuum assist that will connect to the vehicle's vacuum, typically in front of the brake booster. Provided with the install kit will be the necessary adapters, check valve, and air line T to connect the vacuum assisted hose. The control unit here, has the built-in inertia switch and the on-off switch that will get set inside the vehicle; the label here will face the passenger's side, so that the inertia switch is set in the proper position.

It will connect to the operating unit in the vehicle's tow wiring. Another important component here of the Stay in Play system is the break-away switch. The break-away switch is to act in emergency situations, and will automatically throw the braking system into full on, when the switch or pin is pulled out. This will get connected to the tow vehicle, in the case of a break-away or major emergency. Here, we have the actuator that will pull on the towed vehicle's braking pedal, to create the braking. This is an anchor point that will use a self-tapping screw to secure it to the firewall.

Built into it is a clamp and bracket setup that will go around the arm of our brake pedal. Connected to it to operate the actuator will be the hard plastic line that will connect to our vacuum pump from the operating unit. Here is our indicator light that will mount inside the towed vehicle, so that we know when the brake pedal is being depressed. Along with our install kit, we'll have the necessary quick-splice connectors, butt connectors, and ring terminals. Even a quick-splice tap to connect as necessary, and then cover our wires and secure them as necessary, as part of our install kit. Here's the SMI controller.

Again, we have the on-off switch. We'll flip it to on. The mounting location for each of these components will vary from vehicle to vehicle, but we have to make sure that our controller label is facing the passenger side. This application, we've mounted in the rear cargo area. Another good location would be the front kick pannel near the hood release. The operating unit for this vehicle, we've mounted inside and underneath the driver's front seat. We'll slide the seat forward; we'll get a better view of the box. You can also see the vacuum and air line that come out of the front. This will complete the review of the SmI Stay in Play Duo Supplemental Braking System, part number SM99251. .

Easily installed this product myself in about6 hours. This braking system has worked extremely well for me, after using it for over 12000 kilometres, including two trips from Canada to Arizona and then California. Only takes a few seconds to set up , then tow safely. Fully recommend this product, as it gets put in place once, then it is always ready. No need to assemble or remove anything for normal driving operation. 572173

My order from etrailer arrived already today, Saturday! I only placed the order on Wednesday. The website was so user friendly and easy to navigate in helping me find the correct products to purchase to make my vehicle flat towable. When I forgot a very important, albeit small item, I called the 800 number. Preston helped me cancel my original order and then duplicate it, adding the new item to my order so that I would not have to pay for separate shipping. I'm looking forward to having the whole system installed and using it to tow my car with my Class C RV. I would definitely order from etrailer again with all confidence. 562939

I selected this item as an alternative to braking systems that sit in front of the driver seat and must be put in and taken out each time it is used. I like the fact that it is nearly undetectable once installed and works seamlessly. On installation the most difficult part was drilling the holes to screw the unit under the driver seat. The carpet being the primary problem in my experience, as it bound up around the drill bit. 554291

I ordered all the parts required to safely flat tow out 2017 Jeep Cherokee Trailhawk from ETrailer.com. The only part they didn't have was the Mopar Flat Tow Enhancement kit Jeep requires to flat tow this model. Ordering from them was great, the website is easy to use and I was able to locate all the pieces compatible with my specific vehicle. The expert recommendations help my decision choosing the right parts. I ordered from ETrailer even though I found some of the parts on other websites a little cheaper. I chose to pay a little more because of all the effort ETrailer has put into installation videos and guides. I was very pleasantly surprised to learn from ETrailer that they have a price match guarantee! So my equipment consisted of the following Mopar Flat Tow Enhancement Kit (from Jeep) Roadmaster Battery Charge Line Kit for Towed Vehicles Mighty Cord 7-Way RV Style Trailer Connector - Trailer End WesBarg 7-Way, RV-Style Connector w/ 6' Long Coiled Cable Trailer End Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End Hopkins Custom Tail Light Wiring Kit for Towed Vehicles SMI Stay-IN-Play DUO Supplemental Braking System Roadmaster Brake-Lite Relay Kit for Towed Vehicles Blue Ox Alpha Tow Bar - Motor Home Mount - 6,500 lbs Blue Ox Base Plate Kit - Removable Arms Blue Ox Tow Bar Cover - Aladdin, Aventa LX, Aventa II The installation videos are great but not all inclusive. Take the time to read the instructions that come with the parts. This is a major project, I took about 30 hrs over a full week but as you'll see in the pictures I took s few extra steps to make a cleaner look. Some of those extra steps: The base plate install requires the bumper be modified cutting off a flange on each side, I spray painted this to prevent corrosion. In the install video of the baseplate on the drivers side they use an extra quick link (not included) to run the safety cable around the wiper fluid reservoir. I took the time to remove it and run the safety cable behind it. I didn't want our nice new vehicle to look like it can be towed so I played the brake away switch and 7 way trailer plug behind the license plate, so when not being towed our vehicle looks great! Some things to be aware of. The Brake air cylinder that mounts to the brake pedal with four bolts may need longer bolts, it did on our Jeep. Spend the money for weather tight heat shrink crimp fittings. The Hopkins wire harness was about 1.5 feet short to get to my plug location. Buy extra zip ties, electrical tape and split loom. I recommend reading all the various installation manuals and watching all the videos because the various components integrate together and if you install one at a time you'll be doing a bunch of extra work. The brake light relay is a real pain in the butt, not because of the hardware but because of the location of the brake light switch which is very hard to get to. Overall I am very happy with the products and how the installation looks. We haven't towed it yet but do not expect any problems. 410273

This was a great product. With the flip of a switch, I went from normal drive to assisted break towing. From a user point of view, it could not have been easier. The break-assist indicator was located on the dash and therefore seen in the rear camera of the motorhome. I had it installed on a Fiat 500C. While a small lite vehicle, with the braking system, I towed it easily throughout the Rockies and coastal mountains from Oregon to Southern California. Simply a great product. 554603

Not fun to install, but my questions were quickly answered by SMI. Results are great. There is no evidence of the system inside the toad as the control box was hidden in the console. The best way to go if you want effortless connection. No box to place in the driver location in order to tow. Nothing to remove when you want to drive the towed vehicle. 554020

Thanks to installation videos provided by etrailer, I felt confident that I could do the install myself. I had never pulled off moldings and panels in a car before, but with your videos as guidance , it was a breeze. This system was going into a 2016 Ford Edge 3.5L AWD and your (and SMI's) instructions call for installation of 2 check valves. After calling SMI to clarify the install points, it got even easier, as only one valve is required, and is ridiculously simple to install it. No cutting of original car hoses required (see photo). After everything was installed, the whole setup just simply worked, no troubleshooting required. That was fun and it is totally doable, even for the average guy like myself. 403633


Comments

The rear-view camera display in my RV is not good enough to show the operation of the brake notification LED which is applied to the rear-view mirror in the towed car. I installed a small light in the RV dash and ran wiring all the way back to the toad, with a disconnect plug at the hitch, of course. Now it is easy to see when the car brakes come on. Else, the system works great.

SMI Stay in Play Duo installation in 2015 Jeep Wrangler Unlimited – Packaging was great with everything needed included plus extra items for various installation methods of you’re choosing. Upon initial investigation and survey, everything except the CD Information pack was accounted for. No big deal, as I had previously watched 2 different Youtube installations found on the internet. In fact, the internet videos were what I used as my step by step installation process, and the written instructions were only used for concerns where the video may not have been as clear as I had hoped for. Understanding that everyone has their own style and methods for doing this project, I purposely was not in a hurry to rush through it. All in all, I took @ 8 hours to install the Adapter 4 to 6 pole #30637, the EZMount Tow lights Kit, and the Stay in Play Duo Braking System. I choose the EZMount because I didn’t want to mess around with the OEM taillights and wiring. Magnetic lights don’t work so well on composite tops and I didn’t want to stick them to the sides of te Jeep, so I modified the EZ mount to wrap around the thickness of the rear glass hatch on both sides. I added a 2”x 4” pc of Velcro on the inside of the glass hatch and the mating surface of the plastic light housing - to hold the lamps in place until the rear gate was closed. I ran the wire harness on the inside under the trim all the way up to the front and through the grommet in the firewall. The flat 4 wire was routed and secured up to the Adapter 4 pole to 6 pole that I had fastened to the Blue Ox base plate. The actual installation of the SMI unit and assorted parts went rather smoothly. Most difficult issue was the lack of working space in front of the driver’s seat area. Installing the screw that holds the G force controller on the front (the side towards the front of the car) was difficult as it was almost a blind installation due to lack of room. The nut and fender washer used through the fire wall for attaching the air cylinder cable bracket was a challenge to reach - tight fit with not much room for one's hand and arm. Other than that, no big surprises – just a lot of tedious steps to do when you want to be sure that it is being installed properly – take your time and don’t be in a hurry. Once everything was installed – it all worked when I checked the system out. The only thing that may seem a bit odd is that when setting the G force initially, the compressor will shut off while adjusting per instructions. To do this initial adjustment, the wife stepped on the brake in the Motorhome, with the switch “On”. The compressor starts, and the brake is pushed down by the Air Cylinder, at which time I slowly adjusted the G force until the compressor shuts off. I secured the adjusting bolt and I told the wife to take her foot off the brake and then re-apply them. The compressor did not start again and the air cylinder did not apply the brakes in the Jeep. After setting the G force per instructions, the unit didn't turn on when the brakes in the Motorhome were applied - but since we were not moving - all I can assume is that the brake system will function while slowing down once the accelerometer setting (the sensitivity setting on the G force box) has been met. I assume that the sensitivity setting method includes a way to ensure the Jeep brakes are not engaged too frequently and only until needed. This is the only step that is a tad bit confusing without an explanation as to what to expect once the G force sensitivity is set. Lastly, I checked the brake away switch and it turned the compressor on and applied the brakes as expected. Overall - the installation went rather smoothly. Can't wait to see how the product works once we hit the road. I'll check back and provide an update later. 446684

I was a little intimidated by all the parts and different components of installing this product myself, but I decided to give it a try on my 2015 Jeep Wrangler. I did the installation in my garage with just basic hand tools and a cordless drill. I watched the videos from etrailer on different installation applications and then used the written instructions as a guide. The compete install took me about 5 hours and wasn't too bad for someone with average mechanical skills. The only problem I encountered was when attaching the clip for the cable on the brake pedal solenoid to the firewall. The self-tapping screw included with the kit did not hold the clip in place so I had to use a bolt through the firewall with a nut and washer. Ordering and pricing through etrailer was excellent and Heather at the order desk was very knowledgeable and professional. I received my order very quickly (3 days) and I will definitely order from etrailer in the future. 381273

Not being overly mechanical I had the braking system installed in a shop. Once installed and set up you literally do not feel any difference in the amount of braking applied to stop the motor home with the toad attached. Nothing to unbolt or re-install every time you use the tow vehicle is nice. One minor complaint is that I was not advised that the wiring kit needed to wire the taillights in the toad to the motor home braking system is not included and had to stop the installation midway to go out and locate the missing item. Very pleased with this product 184591

Everything installed without any issues. I'm very particular so it took 2 days to complete everything. I'm sure a pro could do it much faster. Have towed the 4" lifted (and loaded) Jeep accross the Rockies about 6 times and everything is working perfectly!! Very happy camper!! 301005

I installed this in a 2012 mini Cooper S. With the turbo charger there is no room in the engine compartment for the system unit, so I mounted it under the passenger seat. I had to remove the seat, cut out the carpet, mount the unit, and then buy longer seat attachment bolts. I used half inch thick spacers between the seat track in the floorboard. Made a long run for the vacuum hose to get up to the engine compartment through the firewall. By removing the cowling on the driver side, it exposes a huge Gromit where the main wiring harness passes through the firewall. It actually had two nipples ready to be cut off to run the vacuum hose and the wires through — so that part was pretty easy. I haven’t towed it behind the motorhome yet, but it passed all the start up tests the first time! 474484

I selected the SMI Stay-IN-Play Duo system after comparing it with the Blue Ox Patriot. The SMI unit has performed as advertised...setting up for towing our Jeep Wrangler Unlimited is as easy as it gets. I didn't want to deal with the hassle and uncertainty of the Blue Ox controller floor placement. After connection to our Winnebago Vista, you flip one switch, attach the LED brake indicator to your rear view mirror, do a brief light check and you'really good to go. I had only one issue that needed attention. While towing, I would intermittently blow the fuse link with the SMI controller unit in the Jeep. A quick call to SMI suggested the solution. Apparently some SMI units needed a slightly higher amp fuse due to the the initial power draw from the vacuum pump when braking. I replaced the stock fuse...15 amp if I recall...with a 20 amp and no more issues. SMI customer service is great and I'm very pleased with my decision! 345933


Comments

Still performing as expected! 5k trip to Colorado and back. Up and down the Continental Divide with no problems. Still the best supplemental brake system for me...both in ease of activation at the RV Park and operation during the drive.

I chose to go with this unit because I didn't like the idea of the other types that mash the brake pedal without any vacuum assist & the fact that you have to remove, then reinstall them each time you want to use the car. This ended up TOUGH install. Not because of the unit, but rather the lack of ANY room under the hood on my 2003 Subaru Outback Wagon to mount the operating unit. The only place I could find that would be out of the way was under the driver's seat of all places! Luckily there was JUST enough hose with the unit to reach all the way to the brake booster. I had to cut the carpeting so the seat would clear the operating unit during movement without any chance of contact. There was no hole in the firewall large enough to accommodate the hose so I had to drill a hole for that although I was able to route the wiring through a small rubber grommet. Routing the hose to the firewall was a real challenge! I ended up running it through the heater duct under the driver's floor mat to the left side kick panel, then up over the pedals keeping clear of any moving parts. WHEW!! The brake pedal actuator went on without much fuss, although with my large feet I have noticed I'll catch the actuator with my toe on occasion. I may mark the location it's in now & merely raise it up a tab in between trips. The wiring was pretty much straight forward, there was plenty of included wire & I had JUST enough room tho mount the G-Force Controller on the left kick panel covering without interfering with my feet. The breakaway switch I fastened to the body in front & below the radiator. I read where everyone was saying you need to have a battery cut-off device to keep the braking system from draining the battery over time, but I had power from the RV keeping the battery fresh so I didn't worry about that & saved myself the $180 for the cost of an automatic battery disconnect. After installation, I sat in the car while we towed it around the neighborhood to see how it worked & made the necessary adjustments to the G-Force Controller. Now THAT was weird! What with the car steering itself & braking too. We just got back from a 4,000+ mile trip & everything worked fine. On occasion I forgot to flip the switch to turn the system off, but it didn't seem to make much of a difference. All in all a great system! 188067

I ordered an entire setup to flat tow my Subaru with my RV. Having never done this before I was nervous about missing something I might need. etrailer made it very easy when I called them on the phone. I told them what I was trying to do and they made sure I had everything needed to complete the job. I was given a name and phone number to call the same person if I had any issues. When one of the boxes was opened it was missing two pins from the manufacturer. A quick phone call and they had them in the mail in a matter of hours. This kind of personalized service is missing in our ever changing world. It was a pleasant surprise to find it here. Great Job etrailer. I will favorably recommend to everyone. 493015

I chose the DUO Stay-in-Play brake system primarily because of a review that convinced me it would be easier to install than my first choice, the Invisi-brake. The overall installation was fairly easy with the great Video that stepped you through the process specific to the 2014 Honda CR-V. There's no way to properly praise the Video. Without it I could not have done the install. There is little to offer in the way of suggestions for improvement, but there were a few moments where things were difficult. If it is possible, without great difficulty, I would suggest including instructions on how to remove the driver's seat, or at least tip it backward, so that one can access the under-dash area easily. Also, I would revise the anchor procedure for the brake actuator to use a through-the-firewall bolt with a fender washer and locking nut instead of the sheet metal screw now used. The firewall metal is just to thin on the majority of vehicles to hold for very long with these forces in play. As much trouble as it is to install this anchor one would be better off to do this right the first time. The Honda CFR-V metal was so thin the sheet metal screw stripped out immediately, requiring the use of a bolt through the firewall. Reaching such a bolt is difficult, but not impossible with the air cleaner cover removed. So far, brake adjustment has been easy and brake is functioning as expected. So long Buddy Brake! You are a good product and have served me well for about 15 years in 3 rigs, but I am tired of taking you in and out!! 271482

The Smi Stay-IN-Play DUO is a great product. I bought and installed it on my Nissan Frontier PU last year. I sold the PU and bought a Jeep Wrangler in October this year.

The attachment of the pulley fixture to the firewall is a bit of a hassle as the self tapping screw has a tendency to round out the hole. Recommend drilling and using a different very short screw so as not to penetrate very far through the firewall. 530109

After doing much research and reading many reviews and watching a lot of your instructional videos I chose the Stay-in-Play Duo. It came complete with instructions and extra parts for any application. I like the fact that after everything is installed it is just a matter of flipping a switch and checking it out and drive off. I mounted it in a 2018 Jeep wrangler, not very much room for the operating unit, but I I went off of one of your videos on a 2017 Jeep Wrangler Unlimited and mounted it underneath above the cross frame below and behind the radiator but still protected from the elements. Not a lot of room under the dash either, but everything is in and looks great and ready for the 1st trip. 518348

This braking system is as easy to activate as flipping a switch. Now the installation, on the other hand, is a project! But, well worth the effort, since an alternative (non-installed) product would be cumbersome having to be positioned and stored in the vehicle. I have a 2015 Jeep Wrangler and the space in the engine compartment is rather tight. I had to fabricate a strap or two to secure the under hood equipment You need to be rather handy with tools and willing to dive in to get it done, but the results are great. The brakes of the towed vehicle apply proportionately without jerking. I did, however, by the radio transmitter-receiver to indicate that the brakes were indeed working because I found that the light supplied with the braking unit was not easily visible in the rear camera of the motorhome. I am happy with this product. 338459


Comments

I am still very satisfied with this braking unit. Since I installed it on the Jeep, we had incurred a rather abrupt panic stop with our motorhome with the Jeep in tow, and the Jeep tracked straight with no bad events. Without the Jeep brakes in operation, I am not sure that we would have avoided a collision. Great product!

Love this braking system. Had it for about a year and towed for about 6,000 miles. DIY install was a bit challenging but totally possible with the excellent video support from etrailer. Every time we connect our tow vehicle all we need to do is plug in the connection to the coach and flip the switch to on. Super easy! The only issue we’ve had is a blow fuse with was easy to fix. The only improvement I could ask for is a brighter/bigger indicator in the tow vehicle. The tiny LED strip is hard to see from the motorhome back up camera especially during bright sunny days. It’s always nice to know that he system is working, so having a bigger indicator or have one that displays in the coach would be nice. 462966

I decided on this braking system because it is pretty much invisible, satisfies the breakaway laws, and keeps a vacuum on the power brake booster. The initial installation took me three or four hours, because everything is so tight in the Chevrolet Spark. I’m sure the time I will save over connecting one of the portable braking units at camp grounds will prove to be significant. Activation of this unit is completed by simply flipping one switch inside the car then tow. Works great. 433925

One issue is the first time out it kept blowing the 25amp fuse a quick call to SMI tech told me to run a 30 amp fuse ok i did and it worked Next trip out blown fuse again and this time the SMI tech told me that some of there units were shipped with a loose ground inside the unit no big deal open it up and yep there was a loose ground wire fixed that issue and then just this last week on a 1500 mile trip the LED indicater light stopped working another call to SMI after a quick diagnosis with the help of a tech it was the led light itself thats went out there sending me a new one with out that light you dont know that the unit in the toad is operating .All this in the first year not exactly install it and forget it . There tech line has been there when i needed them . This is still the best system on the market,it is installed in a 2013 2 door jeep rubicon 428690

This base plate system should be installed using Loctite Threadlocker # LT37420. For your tow bar I recommend the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights # RM-676. This has the safety cables, and a wiring connector integrated into the tow bar system. The LED's give you more visibility when towing your Jeep. For a more economical tow bar...

  • Parts Needed to Flat Tow a 2015 Ford Edge Titanium with 3.5 Liter Motor Behind a Motor Home
  • According to the 2015 Ford Edge owner's manual you can flat tow the 2015 Edge Titanium if it has the 2.7 liter EcoBoost or 3.5 liter motor and 6-speed automatic transmission. Since you have a 3.5 liter then as long as you have the 6-speed automatic you can flat tow your Edge using Blue Ox base plates # BX2667. And for a compatible tow bar I recommend the Alpha, # BX7365. This tow bar also comes with safety cables. For lighting you can use a simple magnetic kit such as # C-ATL20A....

  • Troubleshooting 2018 Jeep Grand Cherokee Automatically Braking When Backing Up with Trailer
  • It sounds like the trailer might be triggering the automatic braking feature on your 2018 Jeep Grand Cherokee. The vehicles brakes are automatically applied and released when going in reverse and the sensors detect a possible collision with an obstacle, and the sensors are mistaking the trailer for a potential obstacle. I took a look at the online owner's manual for your vehicle and it looks like you can override the automatic braking function by pressing the gas pedal, turning the...

  • Recommendations for Towing a 2017 Fiat 500 Behind a Motorhome
  • If you have the automatic transmission, then your 2017 Fiat 500 FWD must be towed using a tow dolly like # RM-2050-1. This is due to the transmission design style to prevent damage. If you have the manual 5 speed, you can tow it as it with a speed restriction of 65 mph. If you have the manual 5 speed transmission, I recommend the following: *Roadmaster EZ2 Base Plate Kit - Removable Arms # 522013-1A *Roadmaster Falcon 2 Tow Bar - Motorhome Mount - 2" Hitch - 6,000 lbs # RM-520 *Safety...

  • Flat Towing Supplemental Braking System Recommendation for 2002 Jeep Wrangler
  • I think your best option would be the SMI DUO part # SM99251. This is a permanent install kit but it's basically the best all around option that would address the issues you have as well. Unlike other similar kits though this one is much easier to install. Based on how it install it won't interfere with the seat either. It also draws power directly from the battery so you'll have the outlet issue avoided as well. I attached an install video for this for you to check out on a similar...

  • Recommendation For Flat-Towing A 2018 Chevrolet Sonic
  • Yes. It is similar and particular parts for 2018 are available. To flat tow a 2018 Chevrolet Sonic, you will need base plates, a tow bar, safety cables, wiring, a braking system, and maybe a high-low hitch adapter. For base plates, I recommend the Roadmaster EZ4 Base Plate Kit with Removable Arms, Item # RM-523192-4 for the sedan with 1.8L engine or Item # RM-523194-4 for the hatchback with 1.8L engine. If you get a sedan with a 1.4L turbo engine then I recommend the Blue Ox Base...

  • I completely understand how you feel. Flat towing a vehicle can seem overwhelming but I am happy to walk you through the parts you will need. The first thing to check is the vehicle owner's manual. I checked it online and on page 266 it states that front-wheel drive and all-wheel drive models can be flat towed! So that is a step in the right direction. You will also want to look through that section of your owner's manual for the procedures required to flat tow your 2017 GMC Terrain. The...

  • Parts Needed to Flat Tow a 2017 GMC Canyon Behind an RV
  • At most the 2017 GMC Canyon will have a curb weight of 4,545 pounds for the 7,500 pound capacity of your Class C RV is more than enough. The truck can be towed with 4 wheels on the ground only if it is a 4x4. If you have a 2-wheel drive model it will have to be put on a tow dolly and towed with the front wheels on the ground and the rear wheels on the dolly.

  • Parts Needed to Flat Tow a 2018 GMC Sierra 1500 Behind a Motorhome
  • We do have base plates for your 2018 GMC Sierra 1500 but # RM-3180-2 will not fit. The comparable set that will fit your 1500 is # RM-3177-3. This set actually has removable arms so that when you take them out the base plates are essentially invisible. I have linked the installation instructions for you to view. For a compatible tow bar I recommend the Blackhawk 2 # RM-422. This is an all-terrain tow bar which means you will not have to be lined up perfectly straight and level to hook...

  • Comparison Of SMI Stay-In-Play Duo And Roadmaster InvisiBrake Supplemental Brake Systems
  • Both the SMI Stay-IN-Play DUO, part # SM99251 and the Roadmaster InvisiBrake Supplemental Braking System, part # RM-8700 are nice braking systems and will function similarly but I recommend the Duo system. Both systems are a one-time installation. The # SM99251 is easier to install because it has a shorter arm that is used in the towed-vehicle where the longer cable used with the # RM-8700 can be tough to find places to mount. I have attached a couple photos that show how the brake pedal...
