You can take it in…but also there are two things that influence the gap at the tailgate. #1. The brackets on the sides that support the tonneau, 3 bolts each side….and adjust. Or #2. Of the tailgate itself does not have the latches adjusted evenly, or the stop is not quite even….and the tailgate can close slightly crooked…and give the same appearance…of a gap. Or it could be a combination of both.
