What is Needed for the Towed Vehicle with the SMI Air Force One

Question:

I purchased a used motorhome that the previous owner had set up with an Air Force One system. In addition to the second car kit, what else do I need to order for a full system? Aside from price, would there be a reason wear or something to just start new?

There are several components that come with the SMI Air Force One Supplemental Braking System for Motor Homes with Air Brakes part # SM99243. The majority of these components get installed on the towed vehicle. If the previous owner did not provide the towed vehicle components and did not remove anything from the motorhome then the SMI Second Vehicle Kit for Air Force One Supplemental Braking System part # SM99209 will be all that is needed.

If they did remove any of the components for the motorhome then you would be best off with a new system. You can check this by taking a look at the parts list in the attached manual. The air lines on the motorhome are not exactly a cause for concern in regards to wear so long as they were installed properly. However, the valves inside the manifold on the motorhome can begin to stick if not maintained properly. It's hard to say if the previous owner's did their due diligence which is a reason as to why you might want to consider a new system.
