When I watched it and the truck pulled up I was thinking it could take some work to get it out with that. But then the tank arrived and I figured it would pull it straight out. Once it got to the stage of trying to snatch recover it with the tank... Well I was just waiting to hear a big crash and see part of the mog flying over the top!
I agree, a higher point on the tow truck would have both lifted the mog out of the mud a little, but also pulled down harder on the back of the tow vehicle giving it more traction. I also thought that a steady pull may have been better than tugging at it? Wet stuff is a pig to snatch things from but a constant pull can sometimes get things moving slowly.
