Having complained and getting nowhere with Winnebago about my Itasca Suncruiser's leak and getting NOWHERE, I figured to come to all of you. I have a driver's side door and a grab handle. There is where it leaked and rotted out the wood under the wallpaper. I found out when the button screw that holds the shade back while driving fell off in my hand. I am a carpenter and have great knowledge of what to look for in regards to sealant leaks and there is none found. Don't have what is neede to do "pressure test". Contacted Winnebago and basically they said [moderator edit]. Not our problem since it was a 2003. What they have no faith on their sealnts???? My house caulking and car stuff has lasted 15 years to date. What should I do? Not rich and can't afford to send it to a certified shop. Can't have this rotted wood either.
