The 2020 GMC Sierra 1500 is available in six trim levels: base, SLE, Elevation, SLT, AT4 and Denali.
The base Sierra comes with a rearview camera, a tilt-only steering wheel, Bluetooth, a 7-inch touchscreen, Android Auto and Apple CarPlay integration, and a six-speaker sound system.
The SLE trim level adds remote keyless entry and an upgraded 8-inch touchscreen.
Stepping up to the SLT adds a MultiPro configurable tailgate, dual-zone climate control, a tilt-and-telescoping steering wheel, a trailer brake controller, heated-and-ventilated front seats, and heated second-row seats.
GMC gives the AT4 trim similar features to the SLT but with a 2-inch suspension lift, standard four-wheel drive with a two-speed transfer case, skid plates, monotube shock absorbers, all-terrain tires, hill descent control, and a terrain-selectable traction control system.
