And the problem with my statement is what? All you have to do is research leaks and eternabond tape 90% of all people with RV's have to fix roofs with eternabond tape because of high failure of rubber roof because of water leaking in. I bet the company is making a good profit The tape gives a 15 year warranty the rubber roof is lucky to get 10. Make you think maybe you should coat the whole roof with the stuff LOL. My buddy's winnie has 14 year on his and still look's like new and never had a leak.
