it takes up most of the space. The bed is 50" wide, and the box is 49.5" wide. Once its in, i'll most likely put in shim boards on the sides and push them up to the cab to seal that spot. I'll also run a bead of silicone along the top of the box to seal it into the cab.looks good man, so does the box take up all the space, so you don't have to seal around it or anything?
