YouTube randomly suggested this min-doc about a missing person who they think was murdered and dumped into a mine shaft. long story short, they picked up this military tank transport truck and turned it into a 30-ton wrecker. it's badass just by itself, but it actually has 8-wheel drive! and the 6 in the rear have some serious articulation, too.
they drive the truck off the semi trailer around 13:30 or so. you get to see the 8-wheel drive and the articulation in action.
