Any new information? I have a Forest River Puma, it is 16 months old. No water access, no heat, just occasional day to day use. Cracks in the fiberglass panel at the lock, every window screw, and some small cracks in the edges of the door.
I spoke with the local Forest River rep, (Giant RV) and they told me this is very common, and I'm SOL. Apparently I can't even order a new panel for self-repair; they're telling me I must purchase an entire door. 700.00. It's just a fiberglas panel, worth maybe 50.00 at the outside.
