Didn't do this, but on our Cougar, noticed the large moulding on the slideout trim was coming loose. Fortunately noticed it before it fell off!
, as I'm sure it would have broken some part of it.
It was just held on by a few nails from a 18 ga trim nailer, so I also used Silicon glue to hold it on, plus the 18 gauge nails. I felt the silicon is at least flexible enough to be pried off, where if I used Wood Glue/Gorilla glue, it would damage the part or other trim.
Wondering if anyone else noticed this on their Slideouts?
