About the 2022 GMC Sierra 3500
4th generation (2020-2023), third model year; a quiet year before the 2024 mid-cycle update.
The Sierra 3500 is GMC’s one-ton heavy-duty pickup, built primarily for substantial towing, payload work and fifth-wheel or gooseneck use. GMC differentiates it with useful bed access steps, the MultiPro tailgate on most trims, integrated trailer guidance and a range extending from basic work equipment to off-road and luxury-focused cabins. Its identity combines commercial-grade capability with more comfort and visual presence than a basic heavy-duty work truck.
The 2022 Sierra 3500 ranges from the straightforward Pro work truck to the off-road-focused AT4 and luxury-oriented Denali. Pro has a 7-inch touchscreen and built-in trailer guidance, while AT4 adds four-wheel drive, skid plates and Rancho shocks. Denali stands out with leather seating, navigation, premium Bose audio and extensive camera coverage.
