We don't have the air bags, but do have a onboard compressor that serves 2 purposes right now; air chuck installed in the running board for uses that you mentioned, and the train horns. May add air bags later. It is indeed very nice. We have a 50' air hose in the truck, so I can adjust the trail air hitch, all tires on vehicle and fifth wheel, plus air up bike tires and toys. Wouldn't be without it.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
