Hmm, that hasn't been posted here before? I saw that video a while back but it's still great. They really know how to wheel. The Lada rolling over was pretty cool. That other vehicle with the tractor tires looks like a YJ rear tub with a TLC front clip on it. The HT is definatly a Jeep. They are very creative up there. They also have a lot of open land that won't get closed off. I love that mud hill. I've driven on some red clay like that and it's very slick. Turns a 2 trail to a 4.5 trail in one good shower.
One of the guy's I've wheeled with had a Sami with Goodyear Tractor tires on there. Seemed to be a good tire for those who rarely drive onroad. Although he was cruising down the highway with them. They don't last long that way though.
