Back home, H1's would get stuck ot the the mud all the time... Too heavy and too wide for mud. The belly would hit the mud, and end of the way for the hummer until it got pulled out.
Moz, I cannot see the video...
I know the H1s are hardly perfect. Do admire the technology on the things: the inboard brakes, 4 wheel indy susension w/ridiculous ground clearance and stability, in-cab tire deflation, ability with water crossings
Of course, the H1 is underpowered (Alpha is little better) and loud. It is a diesel which is give you some fuel options including grease etc, sure. But the H1s power-to-weight ratio makes the 4banger jp seem comparitively quick. And of course, the H1 will get high centered cresting sand dunes, mud sounds like its a problem unless maybe they fit some tires that distribute the weight a little better, the H1's engine is wedged in the middle of the interior, and its just plain big -- manuevering on trails is no cinch if its even possible at all.
