I have been frustrated trying to find the rain water leak at the back end of the wardrobe slide. All the seals around the slide were dry but during a rain storm, I would get wet carpet. This last weekend it was raining and I was determined to find the leak source. After removal of the lower carpet valance, I saw drips coming off the plywood backing but the main lower seal was dry! I went out in the storm on a ladder and checked all the slide exterior seals, they were dry!
As I was descending the ladder, I noticed the rain water was spilling off the topper and running down the side of the slide. At the bottom of the slide there is an angle trim piece running from the outboard edge of the slide all the way into the bedroom. A stream of bubbles was emerging from a small section of the trim piece exactly where the water was cascading down the slide. Hmmmm? Could this be the problem? I covered the trim piece where the bubbles were emerging with some duct tape. When I went back into the rig to check the area where the drips were and AMAZING, they had stopped! Apparently, the water ran along the inside of the angle trim all the way into the bedroom where it was squeezed out by the pressure. A little silicone sealant at the trim piece on the outside has cured the leak!!
