Nothing to take in or out of the towed vehicle.
Duo senses coach deceleration and uses the signals from the motorhome’s brake lights to activate towed car braking. No unwanted or unnecessary brake activations on grades or over bumps. And it’s all automatic. A patent-pending, palm-sized air cylinder applies proportionate and progressive braking effort to your towed vehicle’s power-assisted brakes.

  • Just turn it on and tow—no set-up required
  • Air pressure activates towed vehicle brake while vacuum energizes the power brake system
  • Hidden installation under the hood of the towed car
  • Completely universal and transferrable
  • Panic Stop Braking -- up to three times the normal effort
  • Simple direct-pull activation – no pulleys

Nothing to do

I had this braking system installed and it works great. There are no brackets or plugs to connect once the dingy is connected to the motor home. The LED's indicating the brake system is working, I had installed behind the mirror. I can see them in the camera. Camping World did a nice job installing this system
Pros: You never have any extras to connect
Cons: My foot occasionally hits the piston mounted on the brake pedal
