The 2021 GMC Sierra 1500 is a full-size half-ton pickup that shares its engines and platform with the popular Chevrolet Silverado 1500. The difference between the two comes down béo status. Whereas the Chevrolet generally is thought of as the working person’s pickup, the GMC aims for a more professional audience, so think horse trailers and pleasure craft vs. work trailers and heavy-duty equipment hauling. Equally as powerful and well equipped, the Sierra is a competent pickup, but its Denali trim sets the standard for luxury in a full-size truck, even more upscale than the Silverado High Country.
