Looks like I might have to outfit a new rig at work soon. I'm hoping to find a few different long gun locks (a la Santa Cruz Locks) or lockers / boxes that might fit under the back row of seats in something like a Ford F150 extended cab. I'm hoping to avoid a truck vault, as I need the space in the back, and need a way to lock up my gear.

Anyone have experience with mounting some sort of locking device this way? This will be an unmarked vehicle, no cage, etc.
