Mine is on my hip till I get in, then it goes on the magnet holder on side of hump in the pocket. Easier to get to when in car with seat belt on. I do put mine under back locking seat if I need to leave in car. But I will at some point get a lock box for under seat if one will fit
So I was looking at the truck to see about adding the u-channel and I noticed some what I think are mounting guide points embossed in side wall. Anyone know what might mount there? It's about the same spacing as the boxlink brackets
