I pulled a m920 with a m1009 once. Only had to move it about 1/4 mile, and we had someone in the m920 and an air compressor so he had brakes. We passed a state trooper, surprisingly he didn't do anything. The m920 pushed the m1009 all over the place, I would have been better off putting the m1009 behind the 920 and pushing it. It pushed the backend sideways but I was able to steer it back straight.
Basically, what you have pictured looks really nice and would work just fine----if you had brakes. If you could keep it under 5mph that wrecker truck will still push that truck all over the place if you have to make a turn or go down a hill. If you must do it, put air to the wrecker and have someone sit in it and steer it/work the brakes.
