Brought the rear slide in a bit and pushed the gaskets back to the right spot and extended the slide. Rains continued but no more leak. It would be nice if those stayed put. I may have to look and see if it's something that can be secured, glued, zip tied, duct taped, something...
AugerN.........those rubber seals shouldn't move up and down. If they have movement, put that on your punch list for repair.
They should be secured so they keep water out.
Also, as a side note, it is almost always necessary (at least for me) to manually flip the vertical rubber seals once I deploy the slides. With one exception........the bedroom slide (31UL) has different seals and they never need adjusting.
By flip, I mean pulling the rubber that has curled in when the slide is put in. It is supposed to roll out when the slide is deployed and lay flat against the slide once fully deployed.
Because of the height, I use a 4' step ladder (I carry with me) and a yard stick to slide behind the rubber to the top of the slide.
I hope that makes sense.
I also treat the rubber seals 3-4 times a year with the rubber seal spray offered at any RV dealer to keep them from drying out and staying flexible.
