The MUTT. My brother Fred had to use these, as the Humvees had yet to be deployed, and he hated them, as they had a worse chance of flipping like a cheese omlette than the Jeep's that came before it.
Probably not. Back then cars were not expected to last more than a few years anyway. My guess is it had the life of a rented mule and went to the junk yard still missing the front wheelcover.
