We've illustrated the technique of using a truck (or ATV) to skin a deer in the magazine before, but this is the first video I've found highlighting the practice. Basically, you start by making sure the head of deer is secured to a stout object (in this case, a tree). Then you make a horizontal cut around the deer's neck to free the hide from the carcass and peel enough skin back that you can grab a good handful. Insert a rock or golfball in this wad of skin, and knot one end of a rope around the ball. Attach the other end of the rope to the vehicle and tie that securely. Pull slowly and steadily with the rig, and the hide peels off.
