I have a 2006 23ft Keystone Outback kargaroo and the front and parts of the side is starting to ripple. Is there a fix for this cuz we love our TT but those ripples are really bugging us and it looks like crap. We live in arizona, if it's asked.
I've seen a lot of trailers like this and been told in the past that it wasn't due to water but the sun beating down and the glue separating. Kind of like if you don't keep water in your trailer (for Humidity) while storing, the wall paper will detach itself.
I'm afraid it started a long time ago because that is quite advanced. You must stop the water from getting in, now, then replace everything impacted. At a bare minimum you should cover it so rain doesn't get in anymore.
