Truck shoppers considering the Sierra have vastly different expectations and needs, so it's not surprisingly that this truck comes in hundreds of different configurations, with choices for everything from powertrains, body styles, bed lengths, trim levels, and options. On one hand, you can get a Sierra that merely does the task as a work truck; or you could pay thousands more for a rugged off-road-capable truck or a lavish tow rig.
From Work Truck editions, through SL, SLE and SLT versions, into the luxurious Denali versions, the 2013 Sierra gathers more equipment and progressively plusher interior appointments. At the base level there's a minimum of standard gear:a basic AM/FM radio, and the option to delete it; vinyl bench seat; manual locks; and crank windows. Most Sierras have a standard USB port and an auxiliary jack for media player connectivity; Bluetooth is offered, too. More expensive Sierras now can be had with DVD navigation and real-time traffic data; a sunroof and a power-sliding rear window; 22-inch wheels; leather upholstery; even a factory-installed bedliner.
And at the top of the line, the Denali includes Bose premium audio, heated-and-cooled power front seats, a heated steering wheel, power-adjustable pedals, remote start, a universal remote, dual-zone climate control, rear parking assist, a trailering package, and skid plates. Hybrid models are equipped nearly as well as the Denali (with a navigation system, Bose audio, and leather in a Premium version), while for off-road specialists, the Sierra's All-Terrain package adds on tow hooks, skid plates, and rescue fittings.
