Re: looking at a Skamper AWF on a 1976 Dodge Chasis
First, it was AMF Skamper. They also owned Harley Davidson at the time.
My first MH was a 75 Skamper. Had to send it back to the factory because the walls delaminated and it was never right. The walls are 2" x 2" wooden studs.
If you can get it for a couple hundred dollars and be willing to invest (?) several more thousand...you might have a usable rv. To answer your question...the outside panels can be taken off and put back on. You will have to take it apart completely to do any major repairs. On second thought...ask what they will pay you to take it off their hands.
