I had the same issue with mine but the off-door slideout (heaviest slide) due to motor mount bolts coming loose. It then happened again and then realized it will continue happening. I re-engineered the motor mounts and so far been good. As mentioned above the Carriage-Lifestyle forum will help you out.
