Newbie- we bought a lemon! Delamination issues

I agree with Snowman. Do more on-line research about what products are best to repair,then prohibit leaks. Study those U-tubes and work out the easiest, least expensive strategy. Fix it up as best you can and go camping. You don't have that much in a 10 year old camper and if you can get three or four years out of it, you will be fine. lizzie
