Hmm...I was talking about a H1 though, not a H2. The H1's I saw (5+ in a group) several years ago, they had major issues, they could not spin their tires. Their leader who was conducting the trail run (all but 1 or 2 of these drivers had NEVER even taken any vehicle offroad before, and had just bought a H1) was coaching them, what to do, when to turn, normal stuff. He didn't want to use the winch, so he made them all get through this section with no winch (a good move I'd say to teach them something, but when there were 20+ vehicle waiting, not such a good move). It was crazy, there was black smoke pouring out the exhaust, they were floored, and each tire would move a bit, then stop from the traction control kicking in (atleast that's what the leader, who seemed to know his stuff, said was happening).
It was rather funny and a bit humbling for those drivers, after they spent 45 minutes+ to get everyone through a Toy truck with 33's, rear locker and maybe a 3" lift just walked through it, made it look cake, which it was, but the Hummer dudes had totally the wrong vehicle to have on that trail, but who knows, maybe they learned something that day that you aren't always king of the hill in all situations...and maybe they got rid of their H1 and now own Cruisers..
