I don't follow the H2 bashing. No, it's by no means the off-road monster that the H1 is, but it can definitely hold it's own.
I'll agree that 95% of the people that buy them will put them on nothing worse than an occasional dirt road while traveling to grandma's, but that overpriced "Suburban" has some pretty stout underpinnings...
I've taken an '88 4x4 Suburban places that would astonish you, and with less lift than that Hummer had. Same thing with Nissan Pathfinders, Toyota 4-Runners and an early Land Cruiser ('84; my favorite SUV of the bunch because it was a stick and a TRUE truck). Those definitely fit the SUV category.
Like someone said, if you do any amount of off-roading, no matter what type of monster setup you have, there will come a day when something WILL give...
