Kelly Blue Book saidThe full-size pickup truck segment is one of the most competitive in the automotive world. Despite tough competition from trucks like the Ford F-150 and Ram 1500, the GMC Sierra 1500 remains an excellent choice in this class. It is the mechanical twin of the Chevrolet Silverado 1500, but has its own distinct GMC personality with a different aesthetic and some unique trims. For example, the AT4 trim brings an off-road attitude to the Sierra.
