Last week while washing our camper I noticed a crack had popped up on the sidewall. I have been told that it's from the frame flexing. We purchased it new and this has just now showed up and I haven't towed it anywhere we haven't been at least twice before. Will Forest River help me out with this or will they wash their hands of it? I was told I could split it and insert a trim piece to fill the gap and relieve the pressure. Thanks for any help, and here's a pic.
