I followed the link - turn the truck around and hook the tow bar to the front of the frame, then the truck will follow your running truck and you should be able to tow it with no problems if you are careful. My 47 jeep has a tow bar built on to the front bumper. As you turn, the truck will turn and follow. Hooked to the back like that it will no doubt go out of control.
