Title: Air Force 1 Demco
Post by: Paul Champagne on October 06, 2025, 12:51:06 AM

Hello We need to install a new braking system on our 06 Thunder question is I have a Demco tow bar already on my 2017 Buick Enclave do i have to do any modifications to my Coach as I belive I saw an air chuck by the rear tow hitch . I know the Air Force 1 needs to be installed in my Buick which I would get one of their dealers to do just wasn't sure about the Coach mods...

Anyone else done this with their Beavers?

Thanks

Paul

The Air Force One kit should come with the installation parts for both the car and the coach or if the coach already is equipped you can buy just the car kit.

This link shows the coach kit  with the  pieces to tap into the coach brakes and a reservoir , air pressure regulator and relay valve .
If the coach has the air coupler at the hitch area you should be able to follow the air line back to see the reservoir to see if it's all there.
