RV repair

[va2006spirit]

I have a 2006 Winnebago Spirit, bought use a year ago. These pictures show the rear wall under the coach. The thin aluminum has peeled away from the laminate, exposing the insulation. Has anyone had to repair this area? Any ideas would be appreciated. I added the pictures as an attachment

There is some evidence of water damage which may be the reason it delamniated. That must be addressed first, why it is there and how to stop further damage. Find out what/how the manufacturer attached it to begin with and what to do about it. that might not have been the best way.
If you have two clean surfaces one way may be to use 3M VHB tape.

What is 3M VHB tape?

Will that tape hold up road hazards? This delimitation is below the floor, so debris from the tire will probably hit this area. The center area is fine, just the ends. Thanks for the reply. I am going to contact Winnebago. There is no undercoating under the coach. Is this typical of class C?

I had a 2001 fleetwood jamboree with a similar problem and indeed the separation you mention in my case was related to a leak in the rear shower that I had to repair before this fix as well.
