I have to question some of these sources though, when they list the H2 as being able to climb a "60-degree slope" when it's actually reported (in all Hummer literature) as a 60% grade! ...which, if you do the math, is not even close to the same actual incline.
Also, the H2 is not geared low enough, in my opinion, to handle trail duty and its tie rods are too weak for the weight of the vehicle. In addition, mixing IFS and solid rear axle is a crummy design to begin with. You wind up straddling a rock in the front and then trying to joggle the truck over to put a back tire on the rock in the rear so as to avoid smashing your pumpkin (rear diff) on said rock.
I think the H3 (even though it still has the crummy hybrid suspension) is way better than the H2. Better gear ratio to start with, and much more reasonable size for manuevering on the trail.
Anyway, my rant is over. If you want to see how well the LR3 performs off-road, just take it out and find out. I think people on this board probably know better than these journalists.
