I took a few more pics this evening. Maybe these pics will give those who aren't familiar with my slide and idea of what I'm seeing.
This first pic is the left corner of the slide inside the trailer. On the floor between the slide and the shower stall is where I found the water. When my wife first saw the water she was loading the trailer and the shower had not been used.
This pic shows how the slide sets above the floor.
This pic is an overall view of the outside bottom of the slide.
This last pic shows the bottom outside right corner. Sorry about the pic being out of focus. In the corner you can see there is no seal. I believe this is where the water is getting in.
The whole bottom length of the slide is recessed couple of inches in order to house the three rollers the slide rides on while moving in and out. I can feel along the bottom and everything is sealed well except in the corners.
As I mentioned we had high wind with 60+ mph gust. Very heavy rain at times. I think the rain entered the "channel" at the bottom of the slide and with the tounge high it drained to the right corner and entered the trailer at that point. It's something I need to be aware of, but it's like everything has to be just right for it to happen.
I think the few drops I seen while camping could have come from shower use rather than a leak and the small amount I found when I got home was from the slide being wet when I ran it in.
