My bedroom slide keeps eating the lower seal on the forward roller. I noticed it on the PDI and dealer promised to send a seal to replace it...which I never received. I took the unit to my local dealer and they replaced the seal two different times and it's still eating itself. I plan to take it back in a couple of weeks and, after talking to service mgr., he is going to work with the factory to see what they might recommend on a path towards repair. Honestly it's not a big deal, because it's on the bottom, but it's just not correct.
