I found a rubber seal for garage doors at Lowes that I think will be perfect for the repair! I'm going to rivet it to the existing seal so it will drag about one inch on the top of the slideout.
Yesterday I disconnected the slide topper from the slide and laid it back on top of the MH to get it out of the way. With the slide fully extended I raised the bottom of the existing seal to see what it looked like where the top of the slideout meets the inside fascia. The material on top of the slide turns up maybe 1/4 inch at that point and there is a rubber seal with adhesive back that seals the joint. There was about a foot of the seal that had come loose and water could possibly go over it! I'm putting a large bead of silicone sealant the full length of that joint so if that's been the problem it should take care of it.
I'm about to get out there this morning to finish the job!
