Rippling on my TT

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

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.

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'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...

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.

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.

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.

Yea Keystone is keeping a low level on this and are not doing any repairs, from what I'm hearing..

Ah man, I'm sorry to hear that.
However, if you can remove the trim and siding material, maybe you can re-adhere some new material. It's not hard or expensive work, just time consuming.
The best of luck to you!

I agree with ScottG and if you could get the outer skin(filon) off of the next layer (luan) you could glue it back on with a good contact cement. Just a guess on my part because up here in the pacific northwest where me and ScottG live that trailer would be a total loss due to water damage
