Any recommendations on installing a RIGID 32" gang box (job box) to the bed of 2nd Gen Tacomas?

Is it OK to drill through the floor of the bed to securely mount the feet with bolts? Or are there other methods of installation that will prevent it from sliding around or getting stolen? Thanks.

 

just dont hit anything underneath and you're good. people drill right there for regular toolboxes all the time.

 

I would also put some sort of heavy rubber mat under it. Cut down on any noise or possible wear of the bed .

 

I have the rubber Toyota mat in the whole bed already, so I should be good.

 

OK. Thanks.
