fiberglass delamination
I have a 199ml (20') Keystone Passport Ultralite Express TT that displayed 2 horizontal outward bulges across the back fiberglass wall on a long hot traveling day. They went away that evening as things cooled down. There is no water damage inside or out that I can determine. I am trying to determine if I have a delamination problem or if this is a free floating panel. Keystone says take it to the dealer (a 300 mile round trip) to let them inspect it. This is a long way to go if it's really not a problem. The wall has slight give in it if you press in but it doesn't have the bulges I saw on that very hot day. Any advise out there?
