I'm posting on behalf of some good friends. They have a brand new 5w purchased this spring. Well yesterday while waxing our trailers, he pointed out a small 1/2 x 1/2 " bubble in his laminate sidewall. It reminds me of what a screw popping on drywall would look like, and it has cracked the laminate as well. Any ideas what may cause this? I'm certain now that there is intrusion, it will only get worse. What would be an acceptable fix to resolve this, it is under warranty. I would hate to see a bandaid repair done, only to lead to larger problems down the road. We are camping this weekend but they will take it in Monday, any opinions what they should insist is done? Thanks!
