What do you mean by "recover?" Do you mean literally pull out stuck trucks? Or, do you mean recover vehicles broken down on the highway? If it is the former, they are excellent, provided you don't get stuck yourself. If you are talking about the latter, they are below average as tow trucks. Unless you need to lift the front end off the ground, you are better off flat towing with a 5 ton cargo. Remember, a wrecker is operating on a good day at over the max rated off-road load capacity of a cargo, and that is before you hook anything to it! Imagine what it would be like driving your M813 with about 12,000 pounds of cargo around everywhere you go?!?! I realize they are rated for 10 tons on the highway, but you ain't gonna like the way it drives compared to empty. Wreckers are very cool. I have owned three. I like them all, but they really are better yard cranes or possibly recovery vehicles (as in removing stuck trucks) than they are tow trucks.
