Available exclusively as a Crew Cab derivative, the SLT is the first of the Sierra 1500 derivatives geared towards family duties rather than just being a utilitarian truck. However it’s still able to work hard thanks to the ProGrade Trailering System with a hitch guidance camera. This model gets an upgraded alternator, heavy-duty battery, extra oil cooling systems, and is crucially the first model with access to the 6.2L V8 engine, although you have to spec the 4x4 drivetrain to get it. The driver benefits from a ten-way power-adjustable seat, heated front seats, and a heated steering wheel. Dual-zone climate control is standard, as is the premium infotainment system with wireless Apple CarPlay and Android Auto.
