RV Corner Separation

[Blaster 84]

The corner of my RV is separating. I tried pushing it together and then using an adhesive, that didn't work.
I don't know whether to attempt to put a long screw from the side, or back would hold it in place, or go inside the RV, remove the built-in cabinet in that corner, cut away a little of the wall and screw through a toe plate (if there is one) into the decking.
Does anyone have experience with this and how did you remedy it?

I'll try to post pictures.

We had that problem on our trailer (not FR) at the front seam. A friend removed the trim, did a little searching to find the wood frame, put some long screws in to snug it up, replaced the front trim and caulked.

All the traveling had pulled the screws loose.

You were right. I went to the RV this am and exposed the screw heads under the side moldings. The last screw hole on both sides is stripped. I tried a longer screw, but that didn’t work.
So I moved forward about an inch and started a new hole, that worked.

Thanks.
