Searched on here and saw the MXLocker, but I am wondering ... does anybody make something like thsi but in a chest style box? that way I could keep my tonneua cover? I'm thinking about a bed buddy bolted to a chest-style tool box with some additional bracing. Anybody ever done anything like that before? If I could buy something like the MXLocker in a chest-style box, I'd just do that .... but looks like I might have to improvise.
