I'm not saying our van is heavy, but both front wheels on the tow truck were off the ground. He stopped and called his boss for advice. Finally, he put the bar that goes under the front of a vehicle onto the ground and down for stability. Then it took about 5 tries to get the bed and van to move forward enough to get the fronts down.
When he off loaded us he put that tailhook down first and no problem.
I told CAA the van was 10,000#, and the tow was rated for that but it was interesting.
