Question:

We have a 2019 Tiffin Allegro Bus with air line with Rectus Female end 12mm. We also have a 2026 Jeep that is already set up with Demco Air Force braking system because we bought it when we had a 2026 Tiffin Allegro Bay. What part can I get to change on the MH so that we can use the Demco system.

Welcome back Deb and thanks for all the information! To convert your Allegro Bus's air brakes to work with the Demco Air Force One system like item # DM26VR, you'll need the Coach Air Kit item # SM99627.

Your 12mm Rectus fitting is only a quick connect for the auxiliary air port. That system is not rated or safe to use as a air supply point for the Air Force One system like item # DM26VR.

The Coach Air Kit for Demco Air Force One Flat Tow Brake System item # SM99627 includes all of the specific tank valves, brass fittings, and DOT-rated air lines needed to comply with federal safety regulations. This kit ensures your motorhome's primary air brake supply doesn't fail if the Air Force One braking system does.
