I get a very little water seeping in the top of the slide when it rains like crazy. I believe it is small debris that lifts the seal slightly and gets traped underneath sometimes when you close the slide. almost imposible to sweep every little piece off. However I did find a leak that was driving me crazy recently. Use a hose and start at the lowest point you think water may be entering. spray area and look for leak, if nothing try alittle higher. I made the mistake of starting on the roof and after I sealed, water was still getting in and I couldnt figure it out. Started low and found the water was actually getting in at the trim piece that runs arind the trailerabout 4in above the floor floor. small spot of clear RTV missing. sealed that and the trim screws under the molded piece and no more leek
