Interesting delam issue - revised 6-24, more pics

I would call Eagle Cap, I have read about a few cases with the one piece front caps doing what’s happening to yours.

From what I can tell from Looking at the pic it appears that your’s has a full one piece wrap around cap, though I can’t be sure...Earlier year models used no filon...

It is laminated and the glue has let go this has been on this forum before about eaglecaps. The response from the company was to run some screws into the framing not seeing what year your camper is.

Very seriously doubt it was ever glued filon usually isnt glued. Its why a lot of people see a wrinkle and think its delam.Age heat and gravity is why it appears to be sagging.they used it there so the overhang can flex and not cause stress cracks

Best guess for delamination is poor adhesion, due to contaminated surface, or bad glue procedure /conditions. Add flex and off it came. A section of one of the carbon fiber hulls delaminated on my trimaran. I talked to a highly skilled fiberglass, independent repair person (boat wright / ship wright) who solved my problem. Ask around your area if they have time to do some creative work.

Maybe they could seal it similar to vacuum bagging and see whether it would hold a vacuum. They are very creative. Might need to remove some trim and seal the underlying edges to get the vacuum needed. If so then, pull in low vicosity, slow cure epoxy from one end and out the other. Use mold release (aka wax) to prevent epoxy from sticking on outside visible surfaces. Or creative use of sealing tape.

That would work, assuming you can locate structure?
If the whole lid is coming down possibly use something to help it say up.
Maybe some non-insert trim across full width, or 2?

I have some areas that are not flat anymore. I don’t have a picture handy, but the best way to describe it is irregular with bumps ... I guess. Host said it’s nothing to concern myself with, and there haven’t been any more changes for years.

Sorry, I should have clarified - the entire filon under the bunk has separated. When you poke it with your finger it's a good inch of space in there.
