My kitchen slide does not sit squarely in the opening of the trailer. It is very close to the trailer sidewall at one side on the top and the diagonal corner on the bottom. This was causing it to stick while being retracted and stop. I made some adjustments using the leveling bolts on the slide mechanism (raised one side and lowered the other side) and it helped but I know this is not really correct. Talked with Lippert via Alliance customer service and they really didn't help. I have an appointment to return it to the dealer but would rather make the repair myself. Anybody have any ideas different then what I did?
