        It’s already a truck.

        Sandbags are remarkably effective at stopping small arms fire, at least as long as you can keep the sand in them. If you only stacked up the back wall of the truck right in front of the door and optionally if you only did it to waist height (you’d have to lie down behind them) it would absolutely work.

        A typical hardware store sandbag is 60 or 80 pounds, and to stack up to a height of, say, four feet you’d probably need around 3200 pounds worth of them or so (40 bags) based on some rough back of the envelope math and hazy recollection of the approximate size of an 80 lb bag of sand. That may exceed the recommended load weight of your small box truck per the rental agreement paperwork or whatever the hell, but I don’t think in reality that would cause even a small U-Haul truck to struggle much.

        Doing all four walls of the rear of the truck would probably take an inordinate amount of sand and wouldn’t be too viable.
