I had a similar experience with my kitchen slide on the 369RL although my trailer was 18 months old. Went to extend the slideout and it started to bind. Was able to bring it back in and crawl to the back area of the trailer and found that the metal frame around the fireplace had come off and was laying on the floor. I always check things before using the slides but did not think about the fireplace. Fortunately it did not do any damage and the slide works fine, but now I noticed a few gouges on my floor from the other slideout may have to have that checked out.
