We had a problem with our bedroom slide topper it would not allow slide to extend . Took it to an rv repair shop they adjusted the topper so it has about 4" space between the slide and the awning. It somehow became tight against the slide, tight enough that the topper would bind and not extend. Funny we had no problems with it over the past couple years. I wonder if maybe one of the windy days while extended might have messed with the adjustment?
