Here's a few pics of H1's and H2's off roading.

The H1's look way cool on the outside but they are very uncomforatble on the inside. Very rugged durable vehicle. I have a video of one doing the Rubicon Trial.
I don't like the looks of the H2 at all but I'm sure it is a pleny capable machine due a lot in part to the 35's. It is probably a lot more comfortable on the inside too. But man, those exterior looks are killing me.
The new Jeep Wrangler Rubicon looks really cool and comes with front and rear (and center?) lockers and 31's.
All Jeeps are really capable (except for the Liberty which is a piece of !#$%) I read somewhere that any Jeep model has to cross the entire Rubicon before they can sell it.
The Mercedes G500 comes with solid axles and three independently selectable lockers. But who would take a $75,000 Mercedes off road.
That reminds me of another thing, I don't care how big of tires your H2 has (or the H1 for that matter), it will never be a front solid axle. (Unless you do a swap of course
)
