I'm looking for ideas and thoughts on the following, all of which is legal in my home state and I have a concealed weapons permit: Mounting a handgun holster in the driver compartment, ideally concealed from casual view, where I can easily access the firearm while sitting in the drivers' seat. This is mainly to prevent a would-be car jacking. I'm also interested in a lockable box for the rear cargo area, which would take up about 1/3rd of the available space. I'm intending to store your typical roadside emergency gear but want it to be secured and lockable for other items, including a truck gun. I built one from plywood and 2x4s and it turned out okay, but it's extremely heavy at about 100 lbs. I'd like something of durable plastic that weights a lot less. OR, I once saw a product that replaced the vacant space beneath the rear seats with a drawer. Anyone know of such a product? Thanks.
