We've had some leaking on the bunk ends and used some seam sealer for the areas that are flat that have threads. Our camper has some of the material on the edges (that fold over two seams coming together from the bunk end bottom to the roof) that is deteriorating so water is getting in and running down and soaking the bunk end corners. I "could" get a piece of something and wrap it over it and try to glue it(can't sew it because it would be too thick and make too big of holes with the current stuff on there). It's like a canvas feel material and the outside of our popup actually feels like vinyl. I always get confused...is it canvas or is it vinyl. Anyway..has anyone else had this issue and what did you use to repair it. I can try to post pics later.
