This 2006 Hummer H1 Alpha is one of 729 examples produced for the final model year, 417 of which were wagons. Finished in Black Diamond over two-tone black and brown leather upholstery, the truck is powered by a Duramax turbodiesel 6.6-liter V8 paired with an Allison five-speed automatic transmission and a dual-range transfer case. The truck is equipped with beadlock 17″ wheels, a Central Tire Inflation System, locking differentials, dual fuel tanks, a brush guard, chrome-finished bumper covers, a front winch, a rear hitch receiver, and a full-size roof rack with rear ladders, recovery equipment, and aftermarket lighting. Interior amenities include heated front seats, air conditioning, a Pioneer stereo with navigation, Monsoon speakers, gear racks, and a locking toolbox.

The truck is finished in Black Diamond (B30) and features chrome-finished covers on the bumpers, hood vents, and grille. The seller notes that some areas were touched up under previous ownership, and bubbles are present in the paint where the aluminum body section meets the steel roof.

Equipment includes a front brush guard, a 12,000-pound winch, and a rear hitch receiver. A full-length Gobi roof rack with dual rear ladders has been added along with PIAA lights up front and additional halogen lighting at the rear. The full-size spare, high-lift jack, shovel, and water cans affixed to the roof rack will accompany the truck.

Beadlock 17″ alloy wheels feature rock guards and Central Tire Inflation System center caps. The wheels are mounted with 37×12.50″ Goodyear Wrangler MT/R tires, and the CTIS controls are located in the cabin. All four CTIS valves were replaced to correct leaks in June 2021.

Carpeted gray mats protect the floors and a lighter tan headliner covers the ceiling, which houses Monsoon speakers.
