This is part of a series, you’ll notice the Ute is in pretty poor shape before he starts. That’s because he’s been firing bolt on tow balls at it.
As you say, his message is also keep well out of the danger zone, don’t attach to tow balls of the bolt on kind, don’t use chains and make sure what you attach tobis goingvto stay attached to your rope/strap/winch line as well as to the vehicle.
