All H2s have air ride suspension or?

[HummerMann]

I have the Adventure Package and air suspension on my '06 SUT and I've been VERY happy with it. It all works fine after four years and no problems with anything - the bags are fine and the sensors still work like they are supposed to.
I like the compressor for airing up my tires if you've aired them down (even though it's a little slow), but you will really love the ability to raise your rear if you offroad - it helps your departure angle. Just remember to air back down before you go into the garage if your H2 is a tight squeeze like mine is. They say it makes no difference on the highway ride, but after having an '03 H2 without it, I'm not sold on that statement.
