More About the 2021 GMC Sierra 1500
GMC Sierra 1500 Overview
The GMC Sierra 1500 is a handsome full-size pickup truck with innovative trailering features like a trailer length indicator, a cargo bed viewer, and a jack-knife alert. The crew cab has best-in-class front-row head- and legroom, while cargo bed volume also leads the pack. Some trucks can tow more than the Sierra’s 11,800-pound capacity, but few can match its Duramax diesel that gets up to 30 mpg highway. A Sierra Heavy Duty is also available.
