My Coleman roof

[qwazert]

Greetings, newbie here!
I've been reading and "lurking" for a few days and I thought I'd join in. We are located in the Sotuhwest corner of BC Canada, about 1/2 hour from the Sumas/Huntingdon border crossing.

Since this is the FIXIT section, I've got a problem that I could use some help with!
We own a Coleman Plantation tent trailer - beautiful old gal - my wife loves the shower and full bathroom, the kids love the full-size beds!

Last Fall, We winterized her and folded her up for the season. Next March when we were ready to get going again, I noticed that the ceiling had delaminated near one of the seams!
My first thought was that the roof had leaked but after some investigation, that didn't seem to be the problem...and I surmised that maybe we had packed it up when the canvas was still wet and the moisture had wicked into the ceiling panel (at the joint) because when it's folded up, they'd be in close proximity to each other!
Whatever the cause, now I have a blistered ceiling panel right near the doorway and it's the first thing you notice when you walk in! I thought that I would be able to simply removed the portion of the panel that was ruined, but it looks as though the ceiling panels are GLUED to the styrofoam which is GLUED to the aluminum roof!
Luckily, it is the narrowest of all the panels, maybe 2 feet wide but there's about 6 inches of the full width panel that will have to be removed as well!

Does anybody have a suggestion as to how I can separate the panel from the styrofoam? Once that's done, it should be a snap to replace the panel, but how do I match the pattern? Has anyone tried painting or papering their ceilings?
We may be selling within the next year or so, and I'd like to bring it back to near new condition. Everything inside works and it's a nightmare trying to sell any kind of RV with water stains!

I wonder if you could poke a hole in them and then get some glue up in through the hole you made?  Maybe there's too many to do something like that?

There are syringes made for BBQ-ing and they have a metal needle. Maybe you could fill one with some sort of liquid wood glue and use it to inject a small amount of glue into each bubble, then pull the needle out and press the blister flat with a clean finger or damp rag to mop up any glue that comes back out?

Just thinking outloud....

Problem is, there isn't just one or two little "bubbles" but a whole length of about 3 feet that has de-laminated completely. Even IF I could glue it back together, it would still look like crap!

No, this chunk of ceiling will have to be replaced...
