I Notice before leaving for our trip that the black rubber seal between the slide and the wall was off the wall. There is black goop/caulking but it came off in a couple of places (rubber seal). After looking at it, It looks like there are ridges on the back of it and it would click in when pushed back in. When I put the slide in, all goes back into place and at the campground the seal "mostly" stayed in place.
I didn't do anything to it, going in for warranty work next week (1 exterior speaker, small leak on the awning and this)
Slide not fully extended, see the bow on the black vertical seal
Bottom part coming loose as well
