Two things that I would do. 1. open the slide about 12" pin the topper and close the slide and remove the topper from the brackets and rail. 2. tighten the screws holding the rail and if needed add some fasteners. I would also consider taking a turn off the preset tension on the roller tube to ease the pull on the rail just a thought.
