Let me get this straight, so someone has a leak that is somehow associated with the slide and the basic advice of some is to buy a pc with out a slide?
At the top of the slide, on the corners, there are 2 caps about 5 or 6 inches square, mine were caulked around. Those caps do nothing except cover up a 45 degree seam so it looks nice. Water can get behind those caps, run into the 45 degree seam and run down behind the seal.
Folk, Iím not offended, I just find it.
