I then performed the first of a few pressurized leak tests. The first test showed about 20 leak areas, all of them near windows, through screw holes, or other gaps in the siding. No leaks were found in those areas where Eternabond tape was used. I perform the leak test almost annually and have had no leak problems since. I now believe that Eternabond tapes are superior to any caulk or sealant used.
If I was the OP, I'd clean up the roof joints and apply the tapes. He should have no more sealing maintenance for the life of his trailer.
May I ask how can you perform a "Pressurized" leak test? There are so many gaps, hose line passages, slide-out gaps that I would find it nearly impossible to do so. I would love to know how.
P.S. I really considering to do an Eternabond next spring.
