The 2017 Chevrolet Silverado 1500 full-size pickup is available in three cab styles: the two-door regular cab, the four-door extended (Double) cab and the crew cab. Standard equipment gets a full-width folding rear bench, while crew cabs have a 60/40-split folding bench. Extended- and crew-cab models get power windows and a six-speaker audio system, and regular cabs get manually operated windows and a four-speaker system. The LS adds stainless steel finish wheels, chrome bumpers and grille, power and heated mirrors, deep-tinted glass, power windows, remote locking and unlocking, and the upgraded infotainment system. The LT adds an EZ Lift and Lower tailgate, alloy wheels, body-colored door handles and mirrors, a rearview camera, cloth upholstery, carpeting, a leather-wrapped steering wheel with audio controls, an upgraded driver information display, and an 8-inch touchscreen with HD radio, satellite radio and a CD player.
