Sunroof, Navigation, Sierra 2500HD Denali, Duramax 6.6L V8 Turbodiesel, Allison 1000 6-Speed Automatic, 4WD, Ebony w/Perforated Nuance Leather-Appointed Seat Trim, 20 Forged Polished Aluminum Wheels, 6 Oval Chromed Tubular Assist Steps, Navigation System, and Power Sunroof w/Express-Open. Thank you for taking the time to look at this robust 2011 GMC Sierra 2500HD. New Car Test Drive said, ...If you want the capability of a big pickup with the least sensation of driving a big pickup, the Sierra HD deserves consideration. In a world run amuck for ever-larger trailers and powerplants, it's a sensible alternative for anyone who needs to haul heavy material but doesn't want a Class IV or V truck to do it... This great Sierra 2500HD is the rock-solid truck with everything you'd expect from GMC, and THEN some.
