you can actually do a leak set your self take the top off he roof vent and seal a fan on top then spray the entire camper with a solution of water and dish soap where ever it bubbles there is a leak camping world charged me $250 for a seal test and put chalk marks every where there needed to be new calk. what ever your exterior is it needs to be removed and dried out. I had a forest river product years and years out of warranty, went to the factory in Michigan they did all the repairs plus some they found. When I asked for the bill the reply was when you ever buy a new camper just consider Forest River. I know Michigan is a long way, if it has filon on it that is a job you might need help with. if aluminum you are gold you can remove it dry out everything and put it back together. GOOD LUCK
