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, Truly Proportional Braking

Air Force One is a proportional braking system. When you apply the brakes in your motor home, the system will engage your towed car's brakes at the same time and with the same pressure as those in your motor home, creating synchronized braking.


To achieve this proportional braking, Air Force One ties into your coach's air brakes. The patent-pending process uses air pressure from your coach's brakes to depress the brake pedal in your towed car. The result is uniform, real-time braking that mirrors the slowing or stopping action of your coach. Whether you lightly tap the brakes in your RV or apply them hard in a panic situation, your towed car's brake pedal will be applied in the same manner.


Many other proportional systems activate the towed car's brakes based solely on inertia. With this kind of setup, any activity that affects the forward momentum of your towed car - from the coach actually braking, to driving over a pothole - can activate the supplemental braking system and apply your towed car's brakes. This potential for false braking, which can occur simply from driving over uneven terrain, can create a rough ride for you in the RV and can also wear out your towed car's brakes over time. Air Force One is different, though. Because it is tied into your coach's brakes and is not dependent on inertia, this system activates only when you apply the brakes in your RV, so there is no false braking.


Permanent Installation with Concealed Components

Once you install the Air Force One system, it stays concealed and out of your way - both in the RV and in the towed car. Unlike systems that require you to keep the actuating box under the seat or in the trunk of your towed car, Air Force One does not take up valuable storage space inside of your car. And the components that install on your RV all remain hidden beneath the vehicle so that no room is taken up in its interior either. Because the entire system installs permanently, there is no need to constantly set up and remove this system. You never have to worry about where to store a bulky actuator box when you're not towing. And while most of the components do remain on your Ford Explorer Sport Trac and RV at all times, none of them will interfere with normal driving or braking.


Coach Air Connection Assembly

Because Air Force One uses air to activate, it is a natural choice for diesel motor homes that have air brakes. The coach air connection assembly taps into your RV's air brakes and delivers the air necessary to activate the towed car's brakes through the included coiled air hose. The valves on the coach air connection assembly ensure precise airflow.


Pressure Protection Valve

A 1-way check valve collects air from your RV's brake lines so that it can power your towed car's brakes. This pressure protection valve also ensures that your RV's air lines maintain the same amount of pressure so that the braking in your RV is not affected.


Relay Valves

Metered air from the coach's brakes connects to a service relay valve. This relay valve collects air from your RV's brake lines so that it can power your towed car's brakes. When you activate the brakes in your RV, the delivery relay valve releases the appropriate amount of air to the operating unit in your towed car.


The coach air connection assembly is best mounted in a location on the RV where the air lines will not be near direct heat sources or moving parts, such as in front of the rear axle.


Note: Air Force One is designed for motor homes that have air brakes, but it will also work with RVs that have air-over-hydraulic brakes. Additional parts (not included) may be required for installation on RVs with air-over-hydraulic brakes.


Operating Unit

The operating unit, which mounts in your towed car, receives air from the coach air connection assembly. The unit then diverts a matching amount of air through a hose to the actuating cylinder that mounts on your towed car's brake pedal. That air activates the cylinder so that it applies proportionate braking pressure.


The unit goes under the hood of your towed car, so it is out of your way and always ready. Because this system is a universal fit, you can remove it from your towed car and reinstall it in a different car or truck if needed.


Actuating Cylinder

Small Cylinder

The actuating cylinder depresses your towed car's brake pedal upon receiving the air that is delivered 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.


Coiled Air Hose Connection

Coiled Air Jumper

The coiled air hose, also called a jumper, connects your towed car to your RV by connecting the operating unit to the coach air assembly. When you are ready to hitch up your car and tow it, simply hook up the coiled air hose at the same time as you hook up your tow bar.


Vacuum Pressure Creates Smooth Braking

Normally, when you activate the brakes in your Ford Explorer Sport Trac, 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.


Air Force One reactivates the vacuum-assist function of your car's brakes when it's being towed, even though the towed car's engine is not running. As a result, the actuating cylinder does not need to apply extreme force to the brake pedal to achieve proper braking. The operating unit ties into your towed car's vacuum line with a tee so that it can use the air pressure from your RV to create the vacuum your car needs to brake gently. As a result, no additional vacuum pump is required to create the vacuum-assist function for your towed car's brake pedal. Air Force One 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

AFO Light in Towed Car

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. Air Force One'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.


Air Force One Monitor Install

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 activate when the engine is off, a stop light switch kit (sold separately) is required for accurate notification.


AFO Breakaway

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. A reserve air supply will then apply your towed car's brakes. This system also has "total coach protection" built in. If there is separation, the RV's air supply is sealed off, so its brakes will continue to function as normal.


Air Force One meets Federal Motor Vehicle Safety Standard (FMVSS) guidelines requiring that supplemental braking systems use a separate air supply and activation relay valve.

Video Transcript for SMI Air Force One Braking System Road Test

So we're taking our RV out with our towed vehicle with the braking system installed. The first thing you notice that this proportional braking system does is that when we're applying a little bit of brake in the RV we're getting the same amount of brakes being applied in our towed vehicle. If we're applying a lot of brake pressure, we'll get the matching amount of pressure inside the towed vehicle as well bringing our towed vehicle to a smooth and safe stop in an equal manner with our RV so we don't have to deal with feeling any jerking or pushing of the towed vehicle against the RV. You won't even really feel that it's back there.

I consider myself an average driveway mechanic. Give me a good set of instructions and the right tools and I'll tackle just about any project. But to make sure you don't get the wrong idea, I don't do mechanic work for a living, it's just a hobby. Having said that, the SMI Air force One installation was reasonably straightforward with the exception of the coach air tank assembly. I have a 2005 Itasca Meridian 34 foot DP, and I had a heck of a time finding a space large enough to hang to the tank assembly on the under carriage. Even so, I had to add a brass fitting or two to change routing of the air lines for clearance. After the tank assembly was installed, I fired up the diesel and discovered that my air system would not hold pressure. So I crawled back underneath the motor home and found that I hadn't firmly seated one of the air lines to the tank assembly. Once I reseated the air line, the pressure held steady. I found the instructions to be very helpful, just bear in mind that installations on different brands of coaches may require some ingenuity to make things fit. Personally, I found it took more time to install the equipment in my car than it did on the motorhome. Finding a place to install the operating unit and hoses so they would not interfere with normal engine maintenance takes a lot of thought. Also finding a route from the passenger compartment to the engine compartment is a definite challenge. All in all, the instructions are complete, but it's still a lot of work. If you don't like puzzles, trial and error, and being a contortionist, I would leave the install to the professionals. But if you don't mind bending your body like a pretzel and are handy with tools, go for it. And don't be afraid to call SMI or e-trailer for help. 237647

Vehicle 2016 GMC Canyon Diesel. Installation of the SMI Air Force One supplementary braking system was not too difficult. The instructions from SMI were good as was the video from etrailer. The only reason that I didn't give it a 5 star is because the air cylinder installation on the brake pedal was complicated by an unusual shape of the brake pedal arm. I eventually found a solution. Tapping into the truck's vacuum line was a little difficult but the kit included everything I needed to T into the vacuum line and install the check valves. All in all not a bad installation, this summer we'll see how it holds up. 371137

SMI Air Force One was the choice I made when we outfitted our 2016 Jeep Wrangler Unlimited last year. I can honestly say, without any hesitation,...this was the best choice ever. The installation was very straight forward. I was reluctant to cut my coaches brake lines...but the technicians at SMI were very helpful. I emailed them a picture of the brake lines that I had identified per the instructions, and wrapped a piece of colored electrical tape around the lines to identify them. The SMI techs wrote back within 20 minutes and confirmed that I had correctly chosen the correct air lines for splicing into. The fittings where a breeze to install. The system has performed flawlessly...and it works so well ---- if it weren't for a video camera view on my dash...I wouldn't even know the Jeep was back there. When I go to hook and unhook the Jeep. I keep my components in a canvas bag. It contains my Safety cables for the tow bar, lighting umbilical, and the two SMI parts...a coiled quick connect air line, and a safety breakaway cable. The other components of the system stay in place...no lugging them around. They are totally out of sight. If you have a coach with Air Brakes...this, in my opinion, is the best thing going. Proportional braking...directly metered by your coaches signal line. The system is robust...and includes it's own ping tank, and D.O.T. approved metering valve. I feel it's the safest...and best performing braking system built for a towed vehicle PERIOD. 392190

The service from etrailer was fast and reliable. The SMI Air Force One is a very good system and installation was pretty straightforward. The only problem that I had was mounting the actuator to the firewall. My firewall is made up of two thin layers of sheet metal with a little spacing between the two layers. To me, only using a self-taping screw through one layer of metal wouldn't last long. Unfortunately, I could not drill a hole through both layers of sheet metal to install a bolt through the firewall due to the fact that I would have drilled directly into part of the steering mechanism in the engine compartment. Therefore, I ended up drilling a large hole through the first layer of sheet metal only and then using a small toggle bolt to hold the anchor to the firewall. Once installed, the system works perfectly! 447887

After 1 year of use of the SMI Air Force One braking system I can say I am very happy with this purchase. The only two problems I have had is the air hose disconnecting from the vehicle side, however this is most likely caused by the grill of my Suburban vibrating against the connection. (Just a heads up to those installing. You may need to shave a curved section of the grill to keep this from happeneing to you). Also, the LED brake indicator is not that visible via the rear view camera from my motorhome. Other than that, this is a very fine system, which I would highly recommend. 391687

Great product. I did the coach side install, my local shop did the tow car install. A tight fit under the hood of a Mini Cooper but it worked great. Had a minor problem with the vacuum check valve failing, but SMI was great about sending a replacement to me. (there was some sort of gap on getting registered due to purchasing this from etrailer) Also had to wait longer than I expected to recieved this product.. no doubt was shipped to order to etrailer, then to me... instead of from stock. 372143

I installed this unit onto my 2010 Honda CRV. I did this installation at home. The directions that were supplied were very easy to follow. The operating unit fit over the main fuse panel out of the way. A very neat and tidy package. I used Vancouver Axel &Frame to install the air components onto my 38ft. diesel pusher. This system has worked very well over several thousand kilometers. I have recommended this system to other owners. Very pleased with system and your support. 481006

SMI Airforce one brake system is fantastic. I installed myself direction and kit was first class with everything I needed in the kit. The system performs as advertised and makes flat towing very easy. I just ordered and installed a 2nd vehicle kit so I have my choice of vehicles to be towed. etrailer was the most reasonable and their on line videos were a great help along with their sales associated. I would strongly recommend both E trailer and SMI for your RV needs. 427558

Excellent products, shipped as promised and arrived on time. I have installed all the products. Although it took me longer then a professional installer, I had little to no issues. The online installation videos for all the parts (which were attached to the online order status sheet) made it extremely easy to install. The videos were of a professional actually installing the equipment step by step. etrailer.com has a customer for life. 508326

A word of caution; You cannot wire the brake light, turn signal and tail lights through the the 2015 Silverado wiring harness as these lights are computer controlled, you have to run a separate wiring harness from the tow vehicle to avoid damaging the pickup computer. The new base plates are less obtrusive than the old style and the electronics are smaller and transferable to another vehicle if necessary. Great equipment ! 201099

I purchased a Blue Ox base plate, Air Force One braking system, and a light kit for my 2013 Durango. I could have not asked for an easier process with selecting and ordering, also the tutorials and videos were a great help in determining what was the best system for me . Everything arrived as planned and in great condition. This is not my first time using etrailer.com and my prior experience was equally good. 308970

After using the items I reviewed, about 6,000 miles, I am more than satisfied. The towing setup is easy to hook up and unhook and the braking system is second to none. All of the installation was completed by myself and a friend, both of us have a technical background him more than me and we found the videos of the installation extremely helpful.Thank you for following up and providing excellent products as well as support services.

If your RV has an air brake system this is the only way to go. I researched for days, which way to go with the braking system. After talking to Chris W. at etrailer I decided to go with the SMI Air Force One. It's very compact and out of the way. Thank you Chris W. for giving me all the information I needed..... You guys are the best at etrailer. Adrien A 460945

Great product. It took about 7 hours to install. A complex install so I took it slow. Make sure you have some extra wire handy to make all the connections. Also locate a source for extra DOT air hose, I needed about 15 feet more than included. Not all auto parts stores carry it. The install video on the etrailer site was spot on for a jeep wrangler. 284397

I have the AF1 Installed on my 2015 Jeep Trailhawk. Since installing it along with a Blue OX tow bar, have had no problems and has worked flawlessly. Easy to hook up takes about 5 minutes from start to finish including hooking up the jeep start to finish. I would highly recommend the AF1. It's out of sight and easy to connect and disconnect. 288130

Item arrived in a timely manner. Not installed yet but this has a good reputation. Most if not all of the other brake systems for a toad do not use vacuum assist and for my Accord it is nearly impossible to have braking power without the vacuum. And when you see someone use 'break' for 'brake' give them a virtual dope slap! 380045

After having the Stay-IN-Play for a few weeks in the box a light went off in my head, wrong system. I called etrailer for a return to get the Air Force One because I have air brakes. The return went well and had my new SMI Air Force One in about a week. This is a great system if your coach has air brakes, love it. EZ hook up. 331969

Best brake system I ever bought! Takes seconds to hook up. There’s no need for another device on the dash inside the motorhome. I wish I had bought this years ago. 471893

Review from a similar SMI Air Force One in Tow Bar Braking Systems


Just finished the install of the SMI Air Force One breaking system. Had a couple questions, called the help line and received the info. needed, they were a great help. Installed on a 2008 Monaco M/H and 2015 GMC Terrain. System worked great. Only issue I would have is the pictures and points of tie in for the M/H install could be clearer, thus the reason for the call. I would also like to mention that I have the SMI Stay in Play Silent Partner system that is now over 11 years old originally purchased for my gas M/H and tow and now installed on my 40' Fleetwood diesel and 3rd tow vehicle and still working great with never a down time. I would very much recommend both E Trailer and SMI products. Thanks, Dave G. 171811

Review from a similar SMI Air Force One in Tow Bar Braking Systems


Not too much to say about an air switch. It is required for Toads like mine that power off when towed. It seems to work fine with the rest of the SMI AF1. 172066

  • What do I Need to Flat Tow a Jeep Wrangler JK with Factory Bumper
  • To flat tow your Jeep Wrangler JK behind your motorhome, you will need a base plate kit, tow bar, safety cables, tail light wiring harness, and a supplemental braking system. Depending on the year of your Wrangler, you may also need a Brake-Lite Relay, # RM-88400, (2012, 2013, 2015-2018) or a Stoplight Switch, # RM-751452 (2007-2011, 2014). For your base plates and tow bar, I recommend using the Roadmaster Direct Connect Base Plate Kit, # RM-521448-5 for 2010-2018 or # 1429-3 for 2007-2009,...

  • Installing SMI Air Force One Supplemental Braking System on 40 Foot Dutchcraft on Spartan Chassis
  • When installing the SMI Air Force One Supplemental Braking System For Motor Homes with Air Brakes # SM99243 you will need to find the supply air line and the metered air line. On the Dutchcraft motor home on the Spartan Chassis the larger 5/8 inch line is the supply air line, and the smaller 3/8 inch line below the supply air line is the metered air line. I have attached a photo showing witch line is the supply and which line is the metered.

  • Parts Needed to Flat Tow a 2008 Chevy HHR
  • For your 2008 Chevy HHR you would want a Roadmaster XL Base Plate Kit # 3141-1 like you referenced. The most popular compatible tow bar is the Falcon 2, # RM-520. This base plate kit will bolt onto your vehicle and would not require any welding to install. You will also need safety cables. I recommend Roadmaster safety cables, part # RM-643. These are coiled so they will not drag on the ground. The next component you will need to flat tow the Malibu is lighting. There are actually...

  • Supplemental Flat Towing Equipment and Braking System for Air-Brake Equipped Motorhome Towing F350
  • To safely tow your truck, you'll need a base plate, tow bar, safety cables, a wiring solution to ensure the truck taillights work in conjunction with the coach and a supplemental braking system. I'd recommend the Blue Ox # BX2163 base plate kit and the Blue Ox Avail tow bar, part # BX7420. The Avail is rated for vehicles weighing up to 10,000 lbs, which should be fine for your F350. To wire the taillights of the truck, I'd recommend a bulb and socket kit like part # BX8869. You'll...

  • Recommended Flat Towing Setup for a 2014/2015 Jeep Cherokee Trailhawk Towed by a RV
  • The best and safest way to flat tow your 2014 or 2015 Jeep Cherokee Trailhawk is with a flat towing setup. Tow hooks were not designed to be used for flat towing purposes. There are 5 components to a flat towing setup: Tow bar, base plate kit, safety cable set, tow bar wiring and a supplemental braking system. Base plates are essential and the ones I recommend are the Blue Ox # BX1136 because the draw bars are easy to remove when your Jeep isn't being towed. The most popular and compatible...

  • Should SMI Stay-IN-Play DUO # SM99251 be Replaced with SMI Air Force One # SM99243 for New RV
  • Both the SMI Stay-IN-Play DUO # SM99251 and the SMI Air Force One # SM99243 are great supplemental braking systems that are very popular and have received many 5 star reviews from our customers. The only real difference between these systems is that the Stay-IN-Play DUO is activated by electrical and inertia sensors whereas the Air Force One is activated solely by the air braking system on your RV. I don't have a problem recommend either one so if your Stay-IN-Play DUO is in good...

  • Parts Needed to Flat Tow a 2016 Jeep Cherokee Trailhawk
  • For your 2016 Jeep Cherokee Trailhawk I recommend the Blue OX Base Plate Kit # BX1136. All base plates for your Cherokee will require about the same amount of trimming. I've attached a video of the install on a 2015 Cherokee you may find helpful. You should know that your vehicle may have Mortorq fasteners that require a special bit from Snap-On to remove. I recommend going with the SMI Air Force One # SM99243 for your supplemental braking system. The wireless systems will work but...

  • Flat Towing Setup for a 2016 Jeep Wrangler with a Lift
  • If the aftermarket bumper on your 2016 Jeep Wrangler has the 1 inch D-Ring bumper mounts, which it looks like it does, then you can use the Adapter Lug for Off-Road Vehicle Bumpers to Blue Ox Towbar # BX88296 which is compatible with the Blue Ox Alpha Tow Bar # BX7365 that you mentioned in your question. You can determine if these adapters are compatible by measuring the thickness of the D-Ring mounts. If they are 1 inch thick then these will work great! A complete flat towing setup...

  • Installation Video for SMI Air Force One Braking System for MHs with Air Brakes SM99243
  • My contact at SMI Manufacturing advised that their Air Force One Supplemental Braking System for Motor Homes with Air Brakes, part # SM99243, will soon again have an enclosed installation video disc. Current production does NOT have the disc enclosed as SMI is in the process of preparing an updated installation video. We do have videos that we produced here at etrailer that show the installation process. I have linked those for you. One shows installation in a pickup, the other in a SUV.

  • Recommended Flat Towing System for 2016 Ram 4WD Behind Motorhome with Air Brakes

Automatic transmission trucks should be shifted into PARK and the transfer case shifted into NEUTRAL. Pages 714 through 722 detail the procedures required.

  • Recommended Equipment to Flat Tow 2017 Cadillac Escalade 4WD with RV That Has Air Brakes
  • Flat towing a vehicle behind an RV requires a few items, including base plates, a tow bar and a braking system among others. These and all other items for safe and legal flat towing are outlined in the linked article. To flat tow a 4WD Escalade it must have a 2-speed transfer case that has both Neutral and 4WD Low settings. Blue Ox base plate kit # BX1716 is a good choice for your 4WD. Our in-house installers like the Blue Ox gear. For a tow bar I suggest their Alpha # BX7365 which includes...

This base plate kit will work seamlessly with the Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar - Motor Home Mount - 2" Hitch - 10K, # RM-422 you referenced. I recommend a hitch lock like the # 40107 to secure your tow bar to your RV. For safety cables, I recommend the Roadmaster 80" Coiled Safety Cables - Double Hook - 10,000 lbs - Qty 2, # RM-653.
