They haven't killed it yet!

The techs seem to use it more as a 9800 lb jump box more than a car mover. Still, they've had to move a few cars.

My contact down there sent me photos of them dragging a dead SUV with a locked transfer case off the upper deck of a transport. It had been loaded with a forklift. The tug pulled it down with very little effort despite the trailer going full cheese grater on the four locked tires.
