Just out of curiosity, are there any extended warranty companies that offer coverage for structural type issues...like leaks? I had a 5th wheel that developed leaks due to poor assembly practices at the factory (that was the diagnosis from the repair shop) and now I am seeing things like this on my 8-month new motorhome. I do the inspections and try to catch things early but I may very well miss something along the way. Yes it's still under factory warranty but I am really concerned about everything after the twelve months runs out. I could just have the thing coated with that spray-on roof sealer but how would I get in and out? ?
