exterior rubber molding

If your referring to the small rubber moulding attached to the colored trim piece, it is cosmetic only. It does not seal anything and should not be caulked.

Just noticed exterior rubber molding that joins roof to wall has separated on our '16 Outback. At its widest, the separation looks to be about 1/2 inch and runs for a few feet. In my opinion, 1/2 inch is too much to caulk. Any ideas how to fix this?

That looked a lot like mine. I have some lifting on the front and some like that on the back. I found that Shoe Goo and Goop for RV are seemingly identical products and both act like rubber cement. Even though I was told by NuCamp the rubber is not supposed to be glued to the trailer (just the inside track piece holding it in), I was able to get the goop inside the back pieces, and lay flat, tape them with blue tape, and remove 24 hours later and it worked. They now lay flat, glued to the trailer. Unfortunately, that did not work on the front section. It is still lifted, but not out of the track. To apply caulking or anything inside there would require a pointy tip; it sure is a mess otherwise.
