One other thing to consider on the slides that I just got burned on is to check all the caulking on the outside of it. I had some cracks in the caulking along the bottom of the slide, just above the big trim piece. This allowed water to flow into the slide, not a ton, but enough. The carpets in the slide have this material on the bottom - forgot the name - but basically it acts as mini-insulation against rain when the slide is completely pushed out. However, in my case, it also prevented the rain water that had gotten into the slide from being able to go anywhere. So, it just sits there and occasionally spills over the edge of the carpet onto the house carpet/tile. Going to be a bit of a mess to get it fixed now.
