Window frame not sticking

3M VHB tape, I have a large solar panel held on the roof of our trailer with it.

Am I looking at that wrong? To me it looks like the window itself and it's just open. Close the window, problem solved.

It sure looks like the new frameless window that's open to me.

don't you mean the black window cover {lexan ?}

i would probably get a tube of BLACK polyurethane sealant, put a tiny bead around the frame where the cover is supposed to be
press the cover on and tape it in place until the urethane set
it won't be coming off

or you can leave it at the dealers for a few weeks while they deal with getting the factory to cover the warranty repair

X2. I have found a glue called "shoe goo" to be just about the best glue and sealant I have found. Incredibly strong yet still a tat bit flexible. It's like silicone on steroids.

1 year old class A....start at the source. Probably a warranty issue. I'd call the dealer or manufacturer for a fix or suggestion.
