Filon don't delaminate for just any reason. Usually it's a water intrusion issue with a soaked frame and / or insulation. I'd be looking at the cause first.

thanks

that's why I want to take it off so I can see what the problem is and correct it. my walls are foam with wood laminated to both sides. it its delaminated about 16 in. in from both vertical edges top to bottom and a few smaller spots out in the middle.

Different manufacturers do different things with how they bond the outer skin and a lot of what you need to do will depend on who built it, when it was built and the maker of the skin itself. Every one is different (builders).

You can ascertain if it is indeed a water issue from the inside without tearing anything up. Use a thermal imageing gun or a n IR non contact thermometer and 'shoot the areas inside where the delam appears on the outside. get a base reading from an inside wall where there is no delam. If the issue is water intrusion causing the delam, the areas on the inside that you 'shoot' where the delam is, will be warmee that the 'base' reading from the non delam wall.

Water causes decay in the frame and decay causes heat (and mold) so the wall cavity between the inner wall and the outer skin will be slightly warmer. It always is.

Another way (and something I recommend when buying a used RV), is, look along the bottom of the floor, where the vertical walls intersect the floor (especially behind drawers and inside cabinets. if you see any discoloration of the wall paneling at that juncture, it's water. Additionally, feel along the upper joint between the ceiling and the wall woth your finger for a spongy surface. dead give away it's water.

Filon separates from the substrate for a reason. Might as well eliminate the water issue right away.
