Rippling on my TT

I just did a search on Keystone Delam and its very common in these trailers. here is a similar post on these forums. And Keystone will not fix them and I guess they fixed the issue in the newer models..

It's so ugly and would like to find an easy repair that maybe I can do.

There is one other possibility though rare...
About 6 or 7 years ago another manufacturer, Forest River, had issues with the adhesive they used in thier bonded walls. It caused the classic delamination of the outer skin just like water intrusion did, except there was no rot. If you begin taking it apart and don't find any rot then you may have similar problem but at least the repairs wont be too bad.
I suggest you contact Keystone and see if they'll fess up to anything like this.
FR ended up replacing many walls in affected trailers.

My apologies AZrattle. Where I live is very wet climate that causes delam. It may be possible to reglue that panel if you could seperate it in one piece.

I've looked on top and did a thorough inspection inside to find no water damage of any kind. And it doesn't rain here in Arizona, lol...

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.

The dreaded delamination, not an expert but I think you would have to replace that panel, and find the source of water entry.
