[HummerMann]

I have an '06 H2 SUT bought new from the dealer with the Adventure Package. In '06 the Adventure Package also included special "Adventure Floor Mats" and a nice Adventure tool kit from the factory. I've had no problems with the air suspension and sometimes it will surprise you when it runs to level the H2 after you are getting out with the engine shut off. I do a lot of towing and have had no problems, except the transmission temperature would run 210 in the summer when I was towing, so I broke down and put an aftermarket transmission cooler on. Cheap insurance and an easy afternoon job. The brakes on the H2 are more than adequate for loads up to 5000 pounds.
Here's a good review of the 2008 by Car Gurus if you want to Google it
...... they (the H2) are also one of the best all-terrain AWD vehicles on the road. If H2 owners actually used the SUV off-road, they would find it capable of handling obstacles, steep grades, and deep water as easily as paved asphalt. Towing capacity approaches 7000 pounds. The H2 won the North American Truck of the Year.

The Hummer H2 is also noted for its refined interior features, such as heated leather seats, power seats, dual-zone climate control, and wheel-mounted audio an cruise controls. Most of its life, it got its power from a 6.0 Vortec V8. For 2008, the H2 gets revamped with a new 6.2, 393-hp V8, an updated interior, stronger towing capacity, a standard third row of seats(previously optional), and improved safety features, such as stability control. Though fuel economy remains its biggest drawback, owners say they do feel safe in the H2, thanks to its wide stance and AWD features. The Hummer H2 consistently has the second highest owner satisfaction rating of any American vehicle, just behind the Chevrolet Corvette.
