2022 GMC Sierra HD AT4

This is GMC's heavy-duty pickup, the one you step up to when you need serious towing and hauling capacity. The Sierra 3500HD rides like a proper work truck, with a firm, planted feel that's reassuring when you're loaded up. Inside, the cabin is spacious and comfortable, especially in Denali and AT4 trims, which add upscale materials and tech. You can get it as a regular, double, or crew cab, and with a bed that's built for real work, so it fits a range of jobs. The AT4 is GMC's off-road-oriented heavy-duty trim, sitting above the SLE and SLT with standard four-wheel drive and a lifted suspension. It uses a 6.6L V8 with an automatic transmission and four-wheel drive, giving you strong low-end grunt for towing and trail work. The AT4 adds an off-road-tuned suspension with Rancho shocks and skid plates, so it rides firmer than the Denali but handles rough terrain better.
