Im not so sure that bulge has anything to do with water intrusion. My brand new AF had a few areas near the bottom of the side walls and mine were there since day 1. Mine arent as long as what you are showing, but they are slight bulges. They appear to be where the metal studs are. If you push on them they are solid and tight. If you can do the same thing then possibly they are construction faults and not delamination. Usually with delam the area is soft and can be pushed in.
Hi kerry4951: That is an interesting comment. Here is a picture of the underside of the side right below the bulge.

The floor does not appear to show any signs of deformation. This may only be due to the material used in the floor of the slide (not affected by moisture)?
