We had issues with leaks in some of our slides, and it was always the end windows. Not sure why, but the flange caulking between the window flange and the fiberglass wall surface would shrink enough to cause a paper thin gap where the water would enter into the wall cavity, run down to the floor and then migrate under the wall into the carpet. The first time it happened, even called out a mobile RV guy, and he couldn't pin point where it was leaking. I finally discovered where it was coming from and used silicone caulking around the entire window flange, this at the front window of the large curb side slide. The next leak was the front window of the bedroom slide, a did the same thing to it. One more leak from the rear window of the large cub side slide, and this time caulked every window on the rig, and haven't had a leak issue since. I used automotive black silicone as we have black frames, but clear would also work as well.
