I purchased a project camper for a bargain(I hope) of $250. Yesterday I started my remodel. Pretty much all of the wood needs to be replaced. The metal frame on top is bent from a tree falling on it. Luckily the metal on top is still in good shape and all of the leaks are from the seams and bad caulking. I think I need to replace the fiberglass on the sides as well. Any tips and trick are much appreciated.
