The 2009 Hummer H3T is a midsize crew-cab pickup truck that's available in two trim levels: base and the more powerful Alpha. The base H3T features 16-inch steel wheels, full skid plates, air-conditioning, cruise control, OnStar telematics, Bluetooth connectivity, keyless entry, full power accessories and a six-speaker CD stereo with satellite radio. The Alpha adds the V8 engine, alloy wheels and embroidered headrests.Two packages are available for the base H3T. The Adventure Package adds an off-road suspension, a shorter-geared transfer case for better hill-climbing and descending, front and rear locking differentials, 33-inch off-road tires and a Monsoon audio system with a six-CD changer. The Luxury Package comes with the Monsoon system, leather upholstery, power and heated front seats and oversized floor mats. The H3T Alpha's oddly named Alpha Leather Package has the features of the Luxury Package along with chrome wheels and exterior trim. Major options for both include a power sunroof, an in-dash six-CD changer, a navigation system and a rearview camera.
