FYI -- gleaned from published technical reviews:
A long wheelbase. H2's 122.8-inch wheelbase is almost seven inches longer than a Chevy Tahoe's, while its overall 189.8-inch body length is nine inches shorter than the Tahoe's. On-road, the long wheelbase helps smooth out the ride; off-road, it helps prevent pitching in rough terrain.
The H2's rear axle is the familiar GM 12 bolt solid axle with disk brakes. The base rear suspension is a modified GMT820 5-link setup with variable-rate coil springs and 46mm monotube gas shocks. An optional interactive air spring suspension is available. On this suspension, an air compressor inflates each of the two airbags in the rear independently to raise the H2 in either an automatic, load-leveling mode or by a switch. The compressor uses the H2 20/20 rule, which means that it can pump up all of the tires 20 pounds in 20 minutes.
The front suspension is a GM 25-Series utility truck independent setup using a 36mm stabilizer bar, 46mm monotube gas shocks, and tuned torsion bars.
The H2 has a fully welded ladder-type frame, with a modular, three-piece design that incorporates a number of hydroformed components, for outstanding strength, stiffness and dimensional accuracy.
The front uses a modified GM 2500-Series utility frame. The mid-section is all new and is completely boxed. The rear section uses a modifed GM 1500-Series frame which is upgraded for 8000 pound gross vehicle weight. Front and rear receiver mounts with 9000 pound winch capability are integrated into the frame. The rear hitch has an estimated 7000 pound capacity.
Conclusion: Tohoe's are fine, but the H2 ain't one. Like they say, Ignorance is bliss.
