Main slide leaks. Difficulty getting warranty action

The last thing i would do is put a topper on to cover up the defect.

My last fifth wheel had a leak toward the outside corner of the big slide. i tracked it down to where the trim made the 90 degree corner. Was wide open spaces up there. nothing a generous amount of dicor couldn't fix applied in three intervals.

Why don't you shinny up there sand take as gander. :h
