Repairing water damaged walls

I would go to the local RV dealer first and see what they say. and the dollar amount for the repair. That way you should have an idea, repair it or sell it as is.

Suggest you use the forum search feature and use delamination as your search word - lots of posts on this subject.

For what it's worth - fixing delam issues is usually a PIA often requiring removal of the exterior panel and repair/replacement of damaged interior. After reviewing the various threads you may come to the conclusion that selling the trailer "as is" maybe the way to go .. depends on your skill base.

EDIT

In reviewing your edit it's clear that your talking about interior rather than exterior damage (not delam). Interior issue aren't much different than your stick house. Consider sanding and putting some wallpaper or maybe a thin layer of luan.

Use a knife and cut the wallpaper and pull off. You'll be surprised how easy it comes off. Don't make a perfect square. Make it irregular. Visually you won't see it as easily if you do this. Then cut the new wall paper to fit in the same shape to fit.

Go to an RV dealership service dept. They always have extra wall paper on hand that they will sell you that matches yours.

That's what I did and you can't even tell.

I would sand the bumps down and wallpaper or paint, or a combination of the two.

X2, if you can find matching material.

I have done this type of wallpaper repair described above in a house.

Best way I have found is to tape a new piece over the bad area, and then using a razor knife cut through both new and old at the same time in a random shape. This guarantees the new piece will fit the cutout.
