Ridgid Jobsite Box

I have to agree with this.

Those boxes are damn near bulletproof, but they also scream "easy pawn, steal me, please." It would take a couple of crackheads using the gorilla method of rocking the box back and forth before those bolts pop right through the composite bed. A flat bar or unistrut across 2 bolts means you could practically lift the truck by the box and still not have it break through.

On a slightly related topic, they say the same thing if you're securing a home safe. Before bolting it to the floor make a tight space for it with heavy lumber, so that you can't get a finger on the edge or be able to shove or rock it off it's bolts.

 

I left that picture of my box as a reference to this thread even though it's in the 2nd gen forum since I found it looking for jobsite box pictures. Mine's a 3rd gen, so it might not be as relevant. But with the 42" box, this is where the rear bolts are:



While there may be room to clear unistrut, the pressure would then be on the ends of the vertical fins as opposed to the flat of the floor. Which, that may be stronger still, I don't know. And the 2nd gen bed may be constructed differently than the 3rd's. I remember people saying the tailgate got beefed up over the 2nds, but I don't have anything to compare to, per se.

A lot of contractors run mounted job boxes in my area because they take longer to pry open than aluminum crossover boxes typically. I know I can rock my truck by the job box toolbox, and that's decently secure imo.
