Is that a GM 1500? If so I just bought a 2020 with the same under seat box. I also see you have a “weathertech” style floor liner. How did you make the floor liner fit? Did you cut it or did you remove the box then reinstall on top?
The bolts that are attacht to truck frame for holding jack and tire iron are used to secure the box, I just set it on top of mats and bolted down without issue
