I love the wreckers. I own an M936A2. As crazy as this sounds, though, the wrecker is one of the worst vehicles with which to tow (unless you are towing with the M984 HEMTT wrecker...or possibly the MTVR wrecker). The M543/M62, M816 and M936 are not very efficient tow vehicles because they are way too heavy to really do any towing at any speed of consequence, although to be accuarate, I believe the manual suggests you limit your speed when towing anyway. That is not a problem when the tow vehicle weighs 37,000 pounds! Now, add the weight of the towed vehicle. Think how little top-end power a 5 ton has...now load that vehicle with approximately seven tons. Well, that will give you an idea about what it is like to drive a wrecker even when it is empty.
