The LT trim actually consists of two subsets: 1LT and 2LT. The 1LT adds deep-tinted windows, chrome grille trim, alloy wheels, a CD player, cruise control, full power accessories, cloth seating, keyless entry, an auto-dimming rearview mirror and a leather-wrapped steering wheel. Optional is the burly Duramax 6.6-liter turbodiesel V8, which boasts 365 hp and 660 lb-ft of torque. The Duramax comes paired to an Allison six-speed automatic. Properly equipped, the Duramax allows impressive payload and towing capacities of 5,307 and 16,500 pounds (with a fifth-wheel hitch), respectively. Antilock disc brakes are standard, though stability control, front side- and side curtain airbags are not available. A Safety package that includes power adjustable pedals and rear park assist is optional.
