Regarding the ViAir compressor, we got the 400p-RV model. I saw a video by “Gone with the Wynns” that showed it in action as Jason fixed a tire on his Diesel Pusher while in Alaska, and it seemed to perform well. It runs on 12 v, has 2 sections of hose, is quiet, and amazingly powerful for its size. I figured it would work on any RV, no matter what size. Although it is pricey, it was worth it to me.
