Hi Sabre Sam,
I've got a 2012 FQDS320 and we love it very much. Just took it out of spring storage, everything appears ok, except for the weather stripping around the main slideout. It seems to come unseated from the track stripping (don't know what it's actually called). See image here:
It did it in the fall a couple of times too, so I just popped the weather stripping back in the track with a flat head screwdriver. But it's come back out again.
Any advice on how to correct this issue? Glue perhaps, or maybe a different type of weather stripping.
Thank you very much!
