This fixed my slide leak
This did fix my problem with my main slide leaking and leaving puddles on the floor at both ends of the slide when it was closed through a rain.
Georgetown roughly trimmed the coach side weather stripping tubes at the joints so that they would overlap and meet.
At the bottom corners, the horizontal bottom tube was cut to join the side of the vertical side seal tube. The factory attempted to seal this joint together but it did not hold as the area was not cleaned before sealing. I removed the old silicone adhesive, cleaned with alcohol, and resealed with black silicone adhesive.
At the top joints the vertical side tubes are roughly cut to meet the bottom of the top horizontal seal tube. The factory did not even attempt to seal this joint. From the roof, with the slide closed and the tubes compressed it caused it to leave an opening for water to run down inside the tube. The bottom of that tube is left open so most of the water that would enter would run out, but somewhere in between, some of it was infiltrating into the coach. The first picture is of the top seal joint as it came from the factory from the perspective of me hanging over the side of the roof upside down.
I stuffed paper towels into the horizontal top tube ends, cleaned everything well with alcohol and sealed the joint.
I left the slide out for a few days to set up, removed the paper towel wadding and closed the slide.
I have attached pictures of the top and bottom joints as fixed. The photos make the repairs look a bit messier than by eye.
It has since rained quite a bit with no water inside. Hope this helps!
