Hi all: I'm seeing a lot of threads with slide issues, but not this particular problem...has anyone else out there experienced this with their full slide Fleetwood? The "D" wiper gasket (on front of coach) keeps popping out. The dealer has tried to fix twice now, and it still pops out after 4-5 slides. Once, it caused some binding and the slide came up and hit the ceiling causing a small tear in the ceiling material. This was easily repaired, and it hasn't done that again. However, on a recent trip, it just flopped out again. We pushed it back in and carefully brought in the slide......The gasket is in perfect shape, it's not torn or ragged. It is not affecting the inside and outside seals.... Just at a loss what to try now....

A previous dealer who we don't use anymore told us that it was just a wiper to clean water from the slide when you bring it in....had nothing to do with sealing...but it's a pretty heathly sized gasket....I wonder.
Any experience with this would be appreciated.
Thanks....happy camping.
