This is an FYI for my configuration only.
We returned home on a final leg of 250 miles of moderate bumpy roads. as we started to unpack the rear bedroom slide would only go out a few inches and cock and jam. we tried to open it several times and decided that the motor sounded like it wasn't getting enough power. we plugged in and finished unloading. an hour later it still would not retract.
I pulled the manuals and read up on it. then I crawled in on the mattress to the other side on the slide and looked in the small opening near the rear of the slide. On that side of the slide I have a cabinet and two small drawers, one of those drawers had opened and jammed the slide on that side. we could not see the problem from the switch side and it required crawling over the bedding to get to the problem.
I was not able to get the drawer to return until I used a couple pry bars and a piece of wood to keep from marking the drawer front. The drawer is built like a brick and did not suffer any damage at all. the steel slides on the other hand were bent in U-turns. My dealer said that I caused the damage so I had no claim under warranty. This however was not the end of the world, because instead of the dealer spending a week or more fixing it, I was forced to stop at a friendly Home center where I purchased a set of 12" drawer slides for $4.58 and installed them myself in less than an hour.
I was sweating bullets when I thought the slide system was broken, I ended up almost laughing that I escaped the grim reaper. Phew!
