We are having an issue with our bedroom slide leaking when it rains. The rain runs down the side of the slide, travels up and under the slide out ski, soaking the under pinning resulting in wet carpet on either side of the bed.
We've caulked seams but are still having severe leaks from the bottom.
Welcome to the forum. I'm not familiar with slide out seals. Folks are very visual and if you can post some pics of the problem area you will get good responses im sure.
