The 2016 Chevrolet Silverado 3500HD is offered in regular cab, double cab and crew cab body styles with a choice of two- or four-wheel drive. All cab styles can be had in either single-rear-wheel (SRW) or dual-rear-wheel (DRW, or "dually") configuration. The regular and double cabs are available only with an 8-foot long bed, while SRW crew cab models can be configured with the long bed or a shorter 6.5-foot standard bed. Trim levels start at the base WT (Work Truck), step up to the midlevel LT and LTZ, and top out at the upscale High Country.
Standard equipment for the regular cab WT trim includes chrome bumpers, 18-inch steel wheels, an auto-locking rear differential, rubberized floors, vinyl upholstery, a 40/20/40-split front bench with a fold-down center armrest, power door locks, manual crank windows, cruise control, a tilt-only steering wheel, a 4.2-inch central display and a four-speaker audio system with a USB port and an auxiliary audio jack. The double- and crew-cab WT models get six speakers as standard.
Optional on WT is a MyLink 7-inch touchscreen infotainment system with OnStar, 4G LTE WiFi, Bluetooth, voice controls, satellite radio and Android Auto and Apple CarPlay.
The available MyLink touchscreen interface comes standard on the LT trim and above.
The LT trim adds those optional infotainment features plus an upgraded 8-inch touchscreen, heated side mirrors, tinted rear windows, a remote-locking EZ lift/lower tailgate, remote keyless entry, full power accessories, cloth upholstery, carpeting, a CD player and a leather-wrapped steering wheel with audio controls.

Some features on the upper trims can be added to the lower trims as options. Other extras, depending on trim, include a hard or soft tonneau cover, a sunroof, a Driver Alert package (includes the front and rear parking sensors plus lane-departure warning, forward collision alert and a safety alert driver seat), power-adjustable pedals and a rear-seat entertainment system.
