Interesting delam issue - revised 6-24, more pics

[Boatycall]

My Eagle Cap 1160 filon has let go under the bunk.

But here's the interesting part - I haven't camped in the rain in years, no signs of leaks, and it's fully garaged 24x7.

Input I'm looking for -
Why would it have delam'd?
and..
What would you do to re-glue it? I'm thinking of drilling a couple small holes, shooting it full of glue, then making a reinforced plywood piece that I'll jack up with a floor jack to pinch the filon while the glue sets.

Here's the only pic I could find showing the condition and where I keep it, inside a purpose-built garage---

I think anev942 has the best idear.
I think it would be hard to ensure enough adhesive coverage from a few very small strategically placed holes to endure it stays up.
I “think” it’s heavy plywood sheeting but I’d verify that and use some trim strips. Push it back in place like you’re thinking and sink a bunch of screws in it.
Something like the pic he showed or possibly nice looking washer and screws. Stainless or coated and make it look like it supposed to be ther.

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.
