Looking for some help on this problem: 2021 TRD Off Road 5' bed with BAKFlip tonneau cover. I'm in Canada at the moment and have the bed loaded with camping/fishing gear. Everytime I'm on gravel/dirt I get TONS of dust in the bed which covers everything. I have taped hard plastic door molding to the base of the tailgate (right side on photo) and also attached foam-backed adhesive tape to the end of the bed just beyonf the liner (left on photo). I have also taped the edges of the tailgate before driving on dirt/gravel, which obviously I remove and replace with fresh Gorilla tape whenever I need to open the tailgate. Nothing works.
