Note: This product does not work on vehicles with a non-electric hydroboost braking system.


When using TrailerMate wiring with the InvisiBrake, it will be necessary to purchase an additonal two diodes, (RM-792 - sold separately), to prevent the towed vehicle's brake signal from back-feeding into the InvisiBrake system and activating it when attempting to drive the vehicle.


Fully Automatic Braking Action

Wire the InvisiBrake into your vehicle, connecting it to the battery and electrical harness, and you never have to remove it. When you're ready to tow your car, just connect the it to your RV via the included electrical cable, and the system is ready to go.


The InvisiBrake is designed to activate the brakes in your towed car upon receiving a signal from your RV that the motor home's brakes have been applied. This signal is sent via the wiring harness whenever the RV's brake lights are illuminated. This way, you get real-time braking action, ensuring that your towed car brakes at the same time and for the same duration as the brakes in your RV. In addition, there will be no false braking when you hit bumps or potholes.


Adjustable Pressure Settings

The braking pressure of the InvisiBrake can be adjusted from 5 psi to 80 psi depending on your individual application and preferences. Typically, a braking system has to apply an extreme amount of force to activate the towed car's brakes because the vacuum-assist function of the brakes is not active when the ignition is off. This excessive pressure would cause damage to your car if it had "active" brakes. Because this system lets you adjust the braking pressure to a comparatively minimal amount, you can use it on automobiles that have continuous-power-assist brakes, such as Hummers and hybrids, without having to worry about any potential damage.


The pressure setting needs to be adjusted only once, during the initial installation, at which point you can test the system at different settings to determine which feels best. Once the setting is determined, it does not have to be readjusted, so your system is always ready to go.


Permanent, Out-of-the-Way Installation

Most often, the InvisiBrake actuator box installs beneath the front seat of your towed car, neatly tucked away so that you won't see it and it won't take up any storage space in your vehicle. You can, however, install it anywhere in your towed car that is convenient for you, as long as you can still access the adjustment knob.


A bracket and cable pulley will install on the arm of your vehicle's brake pedal. This will not interfere with normal braking function and does not have to be adjusted, removed or activated. The entire system can stay in your car year 'round, waiting for those times when you need to tow. And once you do hook up your car to your RV in preparation for towing, the system will function automatically.

Video Transcript for Roadmaster InvisiBrake Supplemental Braking System Installation - 2018 Jeep JK Wrangler Unlimited

Speaker 1: Today on our 2018 Jeep Wrangler JK Unlimited, we're gonna be taking a look at and showing you how to install the Roadmaster InvisiBrake Supplemental Braking System, part number RM-8700.Whenever we're flat-towing our jeep, a braking system is gonna be a very important thing. We don't wanna purely rely on our motor home to stop itself and our jeep, so that's where the braking system is gonna take some of the strain and stress off, and it's gonna help reduce the time that it takes to slow down and the distance.Our InvisiBrake is gonna activate the brakes inside of our jeep by having a pulley and cable pull on our brake pedal, helping it slow down. So whenever we push on the brakes in our motor home, it'll activate the cable and it'll pull on the brakes in our jeep. Now the nicest thing about our InvisiBrake is that once we have it installed, we're not gonna have to mess with anything. It's gonna be a permanent installation and this is the most that we're gonna see, is this small bracket that's gonna be at the bottom of our brake pedal. We're not gonna have to worry about moving one of those portable braking systems with those big boxes getting everything perfectly set up inside every time we canna flat-tow our jeep.

We can simply put our jeep in tow mode and hid the road.Our InvisiBrake is gonna have a control unit that we remotely mounted underneath the seat. Now, we're gonna have a gauge here that's gonna let us know the air pressure that's being applied. The yellow knob here is gonna allow us to adjust the braking force either more or less, depending on the road conditions and how we like to have it set.We're not gonna have to worry about any false breaking because our InvisiBrake is only gonna apply the break to our jeep when our brake lights are illuminated in our motor home. Like most braking systems, our InvisiBrake is gonna include a breakaway switch. This is gonna be in case of an accidental disconnect from our motor home, in which case this pin would be pulled and it's gonna apply the brakes at full force on our jeep.Our InvisiBrake is also gonna have a monitor light that we can mount inside our motor home so that way we can always know what's going on inside of our jeep.

Whenever we press the brakes in our motor home, the light is gonna illuminate, letting us know that the brakes are being applied in our jeep. And whenever we let go, the light will go out. Now, there is a safety built into our indicator light. If the brakes are being applied for more than 20 seconds, the InvisiBrake is gonna let go. So if we're sitting at a stoplight where we don't need to have 'em on, we hold 'em for a little bit the light will go out.Now, there's another safety built in.

If we were, for some reason, had something fall on our brake pedal inside our jeep that's constantly holding the brake down, not only is that indicator light gonna come on, but it's also gonna have an alarm letting us know that there's an issue and that the brakes are not releasing.So with a braking system being a requirement almost everywhere we go when we flat tow a vehicle, our InvisiBrake is gonna be a great permanent solution that's gonna keep us within the law and get us safely down the road. So now that we've seen how it works and gone over some of the features, let's show you how we routed everything.Our InvisiBrake is gonna have a control box that we're gonna have to mount. Now typically you'd mount this under the driver's front seat, but in our application we have a safe that's permanently mounted, so we have to find a different spot. So we're gonna mount it underneath the back seat on the driver's side. But we left everything loose so you can see and we can show you how we made all our connections.On the back of the unit, we're gonna have four major components coming out of it.

We're gonna have an 1/8-inch air line and we're gonna have a 1/4-inch vacuum hose attached to it, where we're gonna have a 1/4-inch air line, a four-pin connector with a red and black cable, and then a black cable coming out as well. Then we're gonna have another connector that's gonna have our four-pole wiring attached to it. Now, we just went underneath our seat and we ran all the wires along the edge of the threshold here going behind this panel. Now, this center panel here really doesn't come all the way out, because it is hooked in to where our seat belts are. But we just remove these two pushpins here as well as on the front and tucked them underneath the wire going up towards the front of our jeep.So we just ran our wire up towards the front of our jeep. Now, this panel here doesn't fully come out because our seatbelts are bolted in. So just remove these two pushpins and tuck the wire underneath, going along the threshold.So we just taped all of our wires and air lines together and we ran them straight up to the front. Now, most of these are going to be going outside, but that 1/8-inch air line is going to be getting attached to this air cylinder here. So we just kept everything bundled up and we ran our air line to it. Now, we had to pull up the carpet because on the end of our air cylinder we're gonna have this cable. Now, the cable is what's gonna activate our brake pedal and cause the movement. We follow our cable up, we'll have an anchor point on the fire wall here, and if we go over we'll see that it's mounted to a pulley and eventually on this bracket.Now, mounting up this bracket and that pulley is very important. That's probably one of the most key components of our kid. We wanna make sure that the bracket here attached to the brake pedal is as low as possible, but without interfering with actually pushing on the brake pedal for normal driving. That way it'll have the most torque, being able to pull on that brake pedal and apply the brakes. Specifically for our jeep, the pulley does need to be mounted horizontally. And you just wanna make sure that that cable is centered in the pulley and not off-center, which could cause damage to it. Once you have everything lined up, there's gonna be two nuts on the end of this cable here that we can have slight adjustment, either to bring that cable out or bring it in. But you just wanna have a little bit of play in the cable to where when you push on it, we can see that little ball just barely sticking out.Now for the air cylinder, you just wanna make sure that the cable here doesn't have too many big tight curves in it. You wanna do a big loop to where it's a real gradual curve. And we're just gonna stick all the excess under the carpet, that way it's out of the way. And it just brought our air cylinder back right along the threshold panel, so it'll be hidden once we put that panel back in place.Now for the rest of our air line tubes and wiring, this is gonna have to go to the outside underneath the hood. So we followed it gong along that threshold, and then on the very left hand side of that firewall we're gonna have a grommet. Now we have that grommet because our jeep is an automatic. Normally that's where your clutch master cylinder would go, but since we don't have a clutch, it's a very easy point to go through to get to the firewall. So we sent all those air lines and tubes out through the firewall into the engine bay.Now everything came out just right to the outside of where our brake booster was. To start out with, we'll follow our black and red wire. Now we just ran that along the firewall over to the passenger side, and that's gonna be the power and ground source for our unit. So we took our red wire and we spliced in a fuse holder and put it directly to the positive side of our battery. Then we took our ground wire and routed it along this factory liner here and then put it directly to the negative side of our battery post.For the air line tube that's gonna be coming out, this is gonna be working with our vacuum system. 'Cause if you've ever pushed on a brake pad when a vehicle's off, you know that it can get a lot tighter and harder to push, so our InvisiBrake is gonna work with our vacuum in our vehicle. Now the way we're gonna hook this up is we're gonna find out brake booster, follow the line, and you're gonna wanna find a nice flat spot in there. So we made two cuts: one right at the beginning of the flat spot, and then a little bit farther down. First thing we put in was a check valve right here.Now there's two check valves in your kit, and you're just gonna wanna use whichever one fits the hose that works on your vehicle. Now here's the other one for demonstration purposes, but you'll notice that it has a red stripe on it. The one in there does two, but you wanna make sure that that red stripe is pointing towards the engine. So you put your checked valve in place on the engine cut, and then we'll take a section, a vacuum hose from our kit, and put it on the other end of our checked valve. And then we're gonna have a T that will put it in place, connect the other end of our vacuum line, and then on that third section we'll take some 1/4-inch vacuum line and press that 1/4-inch air line tube into it.So we're gonna have two more cables coming out. It's gonna be that four-pole wiring and that black cable. Now the four-pole wiring is gonna need to tie in to your existing wiring on your jeep. Since we had four-pole wiring already in there and a plug on the front to hook up to our motor home. We simply just routed this towards the front, and you're gonna tie these in color for color for the other wiring. If yours aren't color-coded, the green is gonna go towards your right turn signal, yellow towards your left turn signal, brown to your tail light signal, and white is gonna be your ground.Now the only different between all of our color sis our white is gonna tie in, but we're also gonna have to run a separate ground on this wire. The black cable we routed towards the front of our jeep, then we dropped it down right behind the headlight here and the washer tank so that we can get up to the front bumper.Our cable's gonna meet up with our breakaway switch, and our breakaway switch remounted directly to the front of our brace plate using a short bracket. And you can pick one of these up at eTrailer.com. But we just rounded it down and then along the front of our skid plate, zip tying it behind everything, trying to keep it out of the way the best we can, and then ended up drilling a hole 'cause there's not really a good access point to get through, and then we filled it up with silicone to make sure we keep the wire from chafing and also seal up that hole.There's one more wire that we're gonna need to install, and it's gonna be an indicator light wire that's gonna tap into the cold side of our brake switch. On our jeep we did have to put in a brake light relay so whenever you put your indicator light on, you wanna make sure you tap into the closest side of that relay to the break switch. In this case, it would be on the green wire on the relay harness. We took a buck connector, connected the two wires together, and then ran it back out to the engine bay.So that wire came out that grommet again and we ran it along the same path as our four-pole and our breakaway switch right directly to the front of our jeep. Now normally, you would have that wire just hanging out, and you would have a connector that would match up with this patch cord. This would go in between our jeep and our motor home. However, we took a little bit different approach because let's face it, not everybody's gonna remember to hold on to this, and it can get lost, and it can get damaged. So we wired ours into our six-way so that we can just use the cord that's gonna provide our lighting, it's also going to provide our indicator light. so we wired it into our six-way to the brake controller circuit. Now we can move over to the motor home and wire the other side of it up. But before we do that, let's go ahead and put all our panels back in place.Whenever we go to put the carpet back, you can see that it's gonna be hitting that cable. We're gonna make a couple of relief cuts, then we can get everything back in place so that our cable isn't gonna rub on our carpet. Not only do we need to cut for the cable going across to the pedal, but we also need to make a relief cut for this side of the cable so it doesn't chafe against the carpet.The easiest way to do this is if we just put our carpet loosely back in place, then we can see where everything's gonna land. Then just take a knife and slowly cut away what we need to. We can always cut a little more, but we don't wanna hack up all our carpet if we don't have to.Now we just need to mount our actual box. We do have some tabs on either side that have this little loop in there. And we can take some self-tapping screws and just drill it right into the floorboard. But to prevent having to put more holes into our jeep, what we can do is on either side since it's being mounted to the carpet or by an area that has carpet, we're gonna cut a slit in the carpet just wide enough for these tabs to go in, then we're gonna bend these down, slide it under the carpet, and then press down to bend it flat so it'll hold it in place.On the motor home side, we're gonna have another cable that's gonna match the one that we use in our car, except this one's gonna be about 50 feet long. So on one end, we're gonna start at the back here and we're gonna take our seven-way off. They're all gonna be a little different, but we're gonna need to dismount our seven-way, so we'll take out the mounting screws. Then we're gonna pull it out so that we're gonna get access to the back of it and the wires on the back side.If it has silicone or anything else, we'll then wanna remove all of this so that we can get inside and wire our plugin.Whenever you are removing the silicone or any other kind of material back here, you wanna be careful. You don't wanna damage the wires. You just wanna remove enough so that we can get into the inside of the connector. Then we're gonna remove the screws so that we can open it up.Once we have our seven-way taken apart, we're gonna have a lot of different terminals on the backside. Since we wired our jeep, the terminal we used there was the brake output symbol, so we're gonna be looking for the brake output signal. In our seven-way it's gonna be the blue wire. Yours may or may not have a wire going to it already. If it does, that's alright. We'll just go ahead and take the patch, we'll take the cord. We're gonna cut off the connector on the end here and we'll strip back the end of the wire. So we'll pass it through the connector on our seven-way.And we're gonna loosen up that terminal with the blue wire. Now, you can either remove that blue wire or just add the new cord to it. We'll just loosen up the terminal, we're gonna add that wire from our kit to the brake output terminal. You just wanna make sure that you get your wire nice and tight and that it isn't gonna reach over and touch any of the other terminals. We'll just trim a little bit of it off, slide it behind that plate. Then all we have left to do is put our seven-way back together. Then we're gonna run that wire all the way to the front. Whenever you're routing your wire, you just wanna stay along the edge of the frame rail and zip tie it to some existing wire that's already there. Just stay away from heat sources or any other moving parts.I do wanna mention that since we are eliminating that patch cord and we tied into our seven-way, the only way we're gonna be able to do that is if we don't have a brake controller in our motor home or if that circuit's not being used. If it is being used or you have a brake controller, you're still gonna run everything the same. We're just gonna leave that cord hanging out down here and utilize the patch cord between our motor home and jeep. Then on the jeep side we're not gonna tie into the six-way which again would leave that cord hanging down.We ran our wire up along the frame, then we found this spot right here where all of our factory wire comes in. We just poked a hole, filled it back up with some silicone. Then we ran the wire along this threshold underneath this panel, came up along the weather stripping, and we have our indicator light mounted right there on the dash.In order to get this into place you will need to drill a 5/16 hole in this panel here. It does come down. The way we have it wired up is our indicator light is gonna have two wires coming off it, a red and a white. Then we're gonna have an alarm that's gonna get wired in as well that's gonna have a red and a white. Basically you wanna take the two reds, put them together, and that's gonna tie into that wire that we ran from the back. Then we'll take our two white wires, tie those together, and then we're gonna ground it out to a solid piece directly to the body.So we're gonna line our panel back up, pop it back in place. Whenever you're looking for a spot to mount your indicator light, you do wanna find a spot that's gonna be visible but out of the way where it's not gonna obstruct anything else.Keep in mind this is only one component of a safe flat tow setup. For a complete setup, you're gonna need a base plate, a tow bar, tow bar wiring, a braking system, and then specifically for our jeep we're also gonna need a brake light relay.And that'll finish up your look at the Roadmaster InvisiBrake Supplemental Braking System, part number RM-8700 on our 2018 Jeep Wrangler JK Unlimited.

Good quality materials. Fast delivery Good price. Complicated install. 16 hours labor for me to install toad portion, including bulb kit. 8 hours to install indicator light/warning beeper in RV. Worth the one time effort for me to not have to set and remove floor mounted brake system each time I want to drive the toad. 2002 Jeep Grand Cherokee with electric drivers seat. Controller would not fit under drivers seat, installed in cargo area behind rear seat. Good instructions for install. Kit included everything I needed. Due to controller placement, the controller power leads were not long enough. Air line to air cylinder connection was difficult to get right. Was not as "sure" as air line to controller. Took 3 attempts to get it to not leak. Overall a good product, I expect it will last a long time and be very reliable. 234586

Checked my review today as posted. I mistakenly marked 3 stars, meant to mark 4. Only negative was the hard to make connection at the air cylinder.Everything else was top notch.

The product arrived within a reasonable amount of time. Instruction for installation was pretty good between both what came with the kit and the video etrailer web site. For the most part the installation went well but there are a few things I would like to comment on, and they are: 1) The self tapping screws to install the control unit to the floor of my towed vehicle were too short to get through the carpeting and into the sheet metal with enough bite to hold. Instead I used longer 1/4 - 20 bolts. 2) The vacuum check valve came apart while I was pushing it into the brake vacuum line. I was able to not lose the rubber membrane inside and used super glue to put it back together. I tested it and is working fine but I did order another check valve to the tune of [a few extra] more dollars. 3) It would have been nice to have the etrailer video show something on where to hook up the "Monitor System" from the towed vehicle. It took some doing but I was able to locate the brake switch and tap into the cold side for the signal. Although I haven't put any miles on this system yet my test of it went well. 426007

Thanks for the feedback and review Ken. I wanted to let you know that I have included a link to one of our installation videos and at about the 15 minute mark there are some details about installing the monitoring system in the RV.

A year later and Im still in love with the Roadmaster tow bar & base plate and InvisiBrake braking system. We just got back from a road trip that started around Seattle down to Bryce canyon and back. The tow bar and brake system worked flawlessly, I could not be more pleased. Also, recently I traded in the first Jeep that I installed this system on for a newer Jeep. Knowing that I would be towing the new Jeep as well, I wanted to uninstall the base plate and brake system from my old Jeep and reinstall them on the new. The process went very well, actually faster than the first time I installed it. So, bottom line is that Im very pleased with this set up and would recommend it highly.

This was part of many Roadmaster components I ordered from etrailer.com to set up my 2014 Honda CRV as a toad. Etrailer's website is excellent and their review videos and installation videos are very helpful. Their tech service department is excellent as well. Regarding the Roadmaster Invisibrake, I chose this unit because I did not want anything visible nor any connections to make when setting up to tow or disconnecting. The control unit is hidden under the driver's seat and hardware under the door trim panels. I varied slightly from the etrailer's video in where I mounted the locking clamp and pulley (I did not put the clamp on the raised emergency brake bracket because it was slightly out of line to the pulley that was mounted flush on the floor). Because I choose to route the separate lighting kit wiring on the inside of the vehicle... along the same trim panels and rear trim panels, this made a very convenient place to splice into the wiring next to the Invisibrake control box...nice and protected. The alternative locations of splicing into the lighting wiring harness is under the vehicle....not an ideal place because of road salt, grime and pinch points. I also used the lighting kit with separate bulbs to not interfere with the already installed trailer harness kit for the Honda trailer hitch, nor having to deal with diodes. The Invisibrake works well. I used the extra blue wire in the connecting tow bar wiring harness (7 pin to 6 pin), and the unused brake controller wire in the motorhome that runs to the dash of the motorhome, to operate the signal light. Works great and looks neat. I would recommend that Roadmaster provide some sort of adjustment of the cable at the air cylinder in future generations of this product if possible. This would help on shortening the distance between the mounting clamp and pulley in cases where there is not much room (like in this Honda). Because the only way of taking up the slack now is the combination of the clamp and pulley locations, it somewhat restricts the options on mounting locations and may make some extra work. Regardless of this suggestion, I like the design and initial quality of the Invisibrake and would recommend this unit to anyone wishing to install a supplemental braking system. This does take some pretty good mechanical skills and body contortions to install but if you have that ability...I recommend this unit to the serious do it yourselfer. Otherwise, have a pro install it. 234531

I choose etrailer for this product as the price was very good, they offer videos to assist with the install and technical advise as needed. I spoke with Brandon who was extremely helpful. My order shipped that day and arrived as promised. I am installing it on a Jeep Wrangler that I plan on towing behind my motorhome. 617579

Absolutely love the invisibrake! Used to have an auxiliary brake that I had to install every time I towed. Had to attach it to the brake pedal and get it adjusted "just so". Took up to half an hour and several 4-letter-words to get right. The invisibrake is wonderful! It's permanently installed, and I don't have to do anything with it. It does its job perfectly with absolutely input from me. It is under the driver's seat, so it is not in the way. Also, your prices are very good. 472562

Just received it, and have not begun to assemble and install. I will have a few questions. The shipping was VERY FAST. The unit looks to be in good shape. ( no damage that I can see) etrailer is a very good place to purchase stuff, and spend money. BECAUSE........You get the best value for your money, and they can answer questions. Tom 458127

This Invisi brake system works GREAT. VERY simple to install if you read the instructions. Still have not seen a better deal than what Etrailer gave me.

Have just returned from a 3 week trip using the the Invisibrake. What a great product! With being out of the way( under the seat), it was just plug and play. It takes some time to install but well worth it. 452409

I'am in the process of setting up my 2017 Equinox to tow behind our motorhome. I've placed 4-orders with etrailer. So far I've installed the base plate, the wiring from the rear tail lights to the front end.I also received my Tow bar and the quick release parts. my next project is to install the invisi brake system. I want to send Kudos to Cathy T for her help and her great customer service. I'am also thanking James A for his quick response to a question about the wiring harness. I'am extremely happy with the quality of everything I ordered at etrailer. Thanks 421655

2016 Ford Edge

Installed in 2016 Ford Edge Titanium. Instruction were easy to follow. If installed in the back of the vehicle wire is not long enough. Had to add an additional 4 ft of cable. Cable with the kit is long enough only if mounting towards front of the vehicle or under driver's seat. Mine did not fit under the seat so I had to put it in cargo area rendering the cable too short, had to add 4 ft of cable. Would have given 5 stars if it wasn't for the cable length issue. 364397

Received 1st unit that worked for about an hour until it locked up the brakes. Received replacement but was damaged in shipment, then received 3rd replacement with the mounting tabs damaged in shipment...I was able to repair and use the 3rd unit. Great customer service...Invisibrake works well, but packaging needs improvement. 359328

On my 2015 Jeep Wrangler, this installation is ridiculously difficult. The instructions, while extensive leave out key critical details. The video on this website makes the installation look a lot easier than It actually is. Most difficult is accessing the areas under the dash above the pedals. I would not buy this package again. Otherwise etrailer service, shipping and descriptions are exvellent. 243657

I do virtually all my own maintenance on all 7 of my vehicles. This installation is not conceptually difficult, but working under the dash of a Jeep Wrangler is literally painful. The hardest part is figuring out where to mount the controller and route the brake cable. My Jeep is not the same as the video and I needed to install it a little differently. Take your time here and get it right the first time. I made several modifications to the standard installation - including hooking all the signals (including the Monitor) from my truck camper to my towed Jeep through a 7-Pin RV connector and hooking the power to the Invisibrake through a switch to the battery so I don't have to run my Parking Lights to power the controller. I had a couple questions that the folks at Roadmaster answered cheerfully and professionally. BTW Etrailer is a pleasure to do business with. 228761

Installed in a 2014 CRV. Worst part was getting all the wiring and under the door sill trim panel and routed up through the firewall into the engine compartment, and getting the cable and pulley installed up to the brake pedal. Pretty crowded under the dash in a CRV (my ribs are still sore)! had to use a different clamp on the vacuum cylinder because I had to move it forward of where the video showed in order for the cable to reach the mounting location under the dash. Had to clamp it around the larger end of the cylinder and the supplied clamp would not fit around the larger diameter end. Maybe Roadmaster has shortened the cable? Haven't tested yet but have high hopes! I used the videos extensively, and couldn't have done it myself without them! Not bad for a 72 year old! 221175

Excellent! Have used it towing my CRV on two 2,ooo mile trips since installation. Works very well

Again the etrailer video which I watched many times was very helpful. I did not want the controller installed under a seat so I installed it in the spare wheel well. See attached pictures. This required extending a couple of the supplied cables but that was easily done. Installation was long but went smoothly. I have yet to test it on the road behind my RV. 201945

  • Parts Needed to Flat-Tow a 2019 Jeep Cherokee Trailhawk
  • In order to flat-tow a 2019 Jeep Cherokee Trailhawk you are going to need a base plate kit, tow bar, safety chains, flat-tow wiring, a supplemental braking system, and a possible high-low adapter. I have attached my recommendation on the following parts for you below. Base Plate Kit: Roadmaster EZ4 Base Plate Kit part # RM-521451-4 - This kit has removable arms for a clean look while unhooked from the RV. As long as you do not have the active air shutter system it will work for you....

  • Roadmaster Invisbrake #8700 or Blue Ox Patriot II Supplemental Braking Comparison
  • The Invisi Brake # RM-8700 and the Blue Ox Patriot II part # BRK2019 are both supplemental brake systems but they are pretty far apart in every other way. The # BRK2016 is a much simpler to install setup that works very well. But you have to install and remove it every time you want to flat tow/drive. For this style though it is the best setup. The Invisibrake requires a one-time in-depth install that will take some time, but once installed it works great. If this is more like what you'd...

  • Recommended Toad Towing System for 2018 Jeep Wrangler JL
  • Since you already have the Blue Ox baseplates # BX1139, I recommend using the Blue Ox Alpha Tow Bar # BX7365 which comes with the safety cables you need as well as the hitch pin. If you desire more security I also would add the Blue Ox Base-Plate and Receiver Lock Kit - Qty 4 # BX88177 which will give you the hitch pins for your motorhome hitch as well as a high-low adapter and then the pins for your base plate connections. Then for your tow bar wiring I recommend the Roadmaster Diode...

If you have the automatic or CVT transmission then I recommend the Roadmaster Tow Dolly part # RM-2000-1. This dolly has self-steering wheels to improve maneuvering and electric...

You will need base plates to connect the car to a tow bar, a tow bar to connect the car to your RV, safety cables in case you have a break-away situation, wiring to connect the lights to the RV lights, a braking system for braking, and maybe a high-low hitch adapter for level towing.

  • Will Roadmaster InvisiBrake Braking System Work on 2006 Jeep Wrangler
  • Yes, the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 referenced in your question will fit and work well with your 2006 Jeep Wrangler Unlimited. This is a really nice system that will give you real-time braking in the Wrangler. The actuator box installs permanently so there is no need for removal or adjustments as you transition from flat towing to everyday driving with the Jeep (and vice versa). I have attached an installation video on a later model Jeep Wrangler that...

  • Recommended Permanently Installed Supplemental Braking System to Flat Tow a 2018 Ford Focus
  • On your 2018 Ford Focus I recommend the Stay-IN-Play DUO, part # SM99251, for a supplemental braking system. Mainly because no only does it work well (as does the InvisiBrake) it's a little easier to install. Our installers prefer it to any other permanently installed system. I've linked a video of when we installed it into a 2015 Focus for you. You're also going to need a Brake-Lite Relay, part # RM-88400, to keep the lights of the Focus from overriding the lights of the RV. The...

  • The Roadmaster Brake Master systems can work on a 2019 Chevy Equinox, but only if the motorhome has air brakes. With hydraulic brakes on your 2000 Rexhall, you will instead want a system that is compatible with both your motorhome and Equinox and adding an air compressor to your motorhome will not allow proper braking function. Instead, I recommend using the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 along with the Roadmaster Stop Light Switch Kit # RM-751489. This...

It uses diodes that prevent electrical feedback so no part of your Jeep's electric functions will have any issues. You will also need the Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 which is needed to make sure your Jeep's turn signal lights flash in tandem with your Thor's lights. As...
