One Wheel Drive

A Truck(or any vehicle) that is two wheel drive with an open differential. If a vehicle has a diff locker, positraction, or at bare minimum, limited slip, it can then be considered a two wheel drive. One Wheel drives have no business hitting the trail and off-roading, unless the drivers a crazy fucker like me and is ready to get stuck in menial situations and expend some effort on some vehicle recovery. Oh, but they work great for doing doughnuts on flat ground and haulin dead hookers to the riverbed.
