I used to have to plate all the frames on my 1 ton tow trucks in CO. that I used for recovery work. They would bend and flex till they finally broke usually between the cab and wrecker body. Not much rust there no salt used then only cinders and broken windshields, glass shops were happy lol.

Look at this. This just shows what enough force in the wrong direction can do to you. His whole axle got ripped out, and most likely, he got unibody damage too:

Maybe. But you're talking to a guy with certification in heavy duty towing and recovery. Slow and easy gets it done with the proper rigging and technique.

Used something similar once. Maybe the same product. But they ripped apart. Not worth the money unless they've made drastic improvements.

That video pissed me off so bad

WTF did that idiot take off at 100 mph for?
Many different kinds of vehicles would have been damaged taking off so fast while the vehicle is stuck and pulling at an awkward angle.
