When driving through traffic or rolling down a mountain grade, smooth and even braking makes all the difference. The Demco Air Force One Flat Tow Brake System uses the same air pressure from your RV’s brake line to apply your towed vehicle’s brakes at the same time and with the same intensity. That means no delay and no uneven stops—just natural, synchronized braking whether you’re easing to a light or making a sudden stop. The system meets FMVSS safety guidelines for air-brake motorhomes and keeps your coach’s air supply isolated, so braking performance is never compromised.
Most braking systems overpower the pedal when the engine is off, but this setup reactivates your vehicle’s vacuum-assist function for a smooth, factory-like feel. By tying into the vacuum line and using air pressure from the coach to create the needed vacuum, it lets the pedal move naturally. You get balanced braking without over-pressuring the system or causing wear on the towed vehicle’s components.
You don’t have to guess if your towed vehicle is actually braking. The included wireless Coachlink monitor lights up and beeps in your RV every time the toad’s brake pedal is pressed. Because it connects to a reed switch on the actuator, the alert only triggers when the pedal itself moves—eliminating false signals. It’s a simple, reliable way to keep tabs on your braking in real time and gives confidence that everything is working properly on the road.
If separation ever happens, the built-in breakaway system automatically applies the brakes using a reserve air supply stored in the operating unit. The switch mounts to the front of the towed vehicle, and if the cable pulls free, it activates the brakes instantly. The motorhome’s air lines are sealed off at the same moment, so the RV’s brakes continue to function normally. It’s automatic protection that helps bring the towed vehicle safely to a stop.
This system is built for 2021 and newer Freightliner chassis motorhomes with BrakeSync, which means the coach-side air assembly is already installed at the factory. You simply plug in and go. The operating unit mounts under the hood with a low profile that stays tucked out of sight, and the coiled air hose and 7-foot breakaway cable connect neatly at the rear of the RV. Once installed, the Air Force One stays in place, ready whenever you are—no bulky boxes or repositioning needed.
Flat towing can be a much more convenient way to take your car RVing with you than using a trailer or a tow dolly. It'll save you storage space both at home and at the campsite, and it takes less time and hassle to hook up.
To flat tow your vehicle, there are 5 basic components you're going to need: a tow bar, a base plate kit, a safety cable set, tow bar wiring, and a flat tow braking system.
| For the RV | Between the RV and Towed Car | For the Towed Car |
|---|---|---|
| Hitch | Tow bar | Base plate |
| Wiring plug | Safety cables | Braking system |
| Wiring adapter cord | Wiring kit/diodes |
The custom-fit base plate installs on the frame of your toad so you can connect the car to your RV with a tow bar. Hook up safety cables between the vehicles to ensure that the toad does not separate from the motorhome if the tow bar becomes detached. Tow bar wiring syncs your vehicle's signal lights with your motorhome's tail lights, as required by law in most states. Finally, the flat tow braking system - also required in most states - activates the brakes in the toad when you hit the brakes in the RV, making for smoother, safer braking, and preventing wear on your motorhome.

This braking system is the best I have used since I started RVing 10 years ago. It has worked flawlessly over the past year and I recommend it highly.
