I have the same concern with my rig. I'm getting a small leak under my bed and night stand near the rear of the coach. I've calked the trim on the lower right rear corner of the slide, which helped some. With the slide out I can still see water dripping on the inside of the trim, underneath, which then makes its way into those open drain channels and into the coach. When it rains, the water really comes off the rear right corner of the roof and runs down the side of the coach. Any suggestions would be appreciated. Oh, and the rubber seal buckles under at the rear right corner when the slide closes. I've sprayed it with conditioner and it still buckles under for about a couple of feet.
