Same thing happened to mine only the trim fell off while washing it in the driveway. Only 1 of 3 screws holding it on other two were not screwed into anything. I used 3m 4200 marine sealant. Expensive sealant but it's adhesive strength is superior to just about everything else, except 3M 5200 which is a forever fix and can not be removed should you wish to do so in the future. There is a solvent made specifically to remove it, but not worth the effort.

I assume it is made to have some give and flex as I see that as a requirement for this area? I have the three screws but have not checked how well it is attached yet?

JamJanTan, I don't see the need for flex in this area. By the way, the other side was not loose but had a gap that I filled with a clear sealer, don't remember the name of it, but I works well wet or dry. So far so good.

Just thinking that traveling down the road at 65 MPH that area is going to have some stresses on it. But I have heard mention of the marine adhesive sealant in several other posts so may give it a try. Thanks

2nd for the 4200 although I would probably go with 5200 as I see no need to take it apart.

Think you are probably right about no need to take apart but ordered the 4200 so be it. What thinks everyone about a good all purpose sealant to seal all joints with each year. Hopefully not as expensive as 4200.

I just used Gorilla Glue on some of our loose trim. Other than expanding a little (which I knew it would) it has good hold and is a great value.

Something to keep in mind. Iím thinking whether I need to clamp the trim over went I patch or just fill with glue.

You'll definitely want to get that piece back into place...
Can you use Duct Tape; to secure it, while it sets up?

I used clear packing tape on ours when I did the trim reglue. I would think that duct tape would also work, I am always leery of having residue after putting tape on the walls.

You could try using the blue painter's tape: supposed to be easy to remove and no residue.

The packing tape, when pulled tight, keeps tension on the seam like a clamp would. Fold over a small tab to ease removal.

keep a close eye on that short piece of trim that returns back towards the cab door.
On my passenger side, I discovered that trim looked a bit loose. Turned out that that whole wall had rotted out. You couldn't tell from the skin.....

Turned out to be two problem areas up on the roof that had been leaking. The skin that forms the nose of the cab over was cut short and had almost zero surface area under the corner trim up near the top where it joins the roof
and
the roof membrane at that same corner was a bit short and also had a screw under that insert trim that wasn't sealed.
No apparent damage in the cab over or side wall that I could find. i think the water dripped down framework in that exterior non-wood wall in mine and got into the plywood in this little return wall.

I'd suggest
taking that trim off so that you can see the bottom edge of that plywood core
and
I'd suggest taking the upholstered panel that covers that wall on the inside off to have a look at the plywood. (mine was "buttons" on a pillowed vinyl covered wall). Those buttons are nothing more than covered snaps that pry right off to reveal a screw. very easy to remove for a look.

I sincerely hope you don't find what i did.

Thanks for the info. I will be sure and take a look before I seal it up. One thing I have done that I hope help with these sort of things is RV gutter. I basically have water running off the sides only at the corners of the rig which I try to keep a class eye on. I am considering running gutter across front and back to prohibit water intrusion as much as possible. Thanks for the heads up making repairs next weekend then opening 2018 camping season the next weekend. Happy camping.
