The 2020-2023 GMC Sierra 3500HD V (GMTT1XX) Crew Cab Standard Bed has an impressive overall length of 6352 mm (250.1 inches) and a width of 2079 mm (81.8 inches) with the mirrors opened. These dimensions contribute to its commanding road presence and spacious truck bed, making it ideal for heavy-duty tasks while maintaining road stability.
This generation of the GMC Sierra 3500HD measures 2054 mm (80.9 inches) in height. It features a ground clearance (or ride height) of 284 mm (11.2 inches). This substantial ground clearance provides excellent off-road capabilities and the ability to handle rough or uneven terrain while transporting heavy loads.
The curb weight of this model ranges from 3015 kg to 3573 kg (6644 lbs to 7875 lbs), depending on configuration and additional equipment. Its maximum gross vehicle weight rating (GVWR) ranges between 4604 kg and 5489 kg (10,153 lbs to 12,100 lbs), reflecting its robust design intended to handle significant payloads and towing demands.
Various tire sizes are compatible, including 265/70 R17, 245/75 R17, 275/70 R18, 265/70 R18, and 265/60 R20. Corresponding rim sizes are 7.5J x 17, 8J x 17, 8.5J x 18, and 8.5J x 20 inches. These options offer flexibility for balancing ride comfort, off-road capability, and load carrying.
The Sierra 3500HD V's large size makes garage fitting challenging. With a length of 6352 mm (250.1 inches), width of 2079 mm (81.8 inches) including mirrors, and height of 2054 mm (80.9 inches), many standard residential garages (typically about 2438 mm/8 feet wide and 6096 mm/20 feet deep) are too small. Custom or oversized garages are recommended to house this pickup comfortably.
Compared to the previous generation Sierra 3500HD, the 2020-2023 GMTT1XX generation is notably longer and wider, offering enhanced cabin space and increased bed length. Height and ground clearance have also seen modest increases to improve off-road capability. This generation reflects GMC’s shift toward combining heavy-duty utility with enhanced driver and passenger comfort.
In direct comparison, the Sierra 3500HD V's length of 6352 mm (250.1 inches) aligns closely with competitors like the Ford F-350 Super Duty, which ranges from approximately 6160 mm to 6700 mm (242.5 to 264 inches) depending on bed and cab configuration. The width of 2079 mm (81.8 inches) is on par with these rivals. Height and ground clearance are competitive, with all models designed to handle heavy-duty workloads, although GMC offers a slightly higher ride height advantage for off-road capability.
Several features contribute to its heavy-duty suitability: a robust frame, a maximum gross vehicle weight rating (GVWR) up to 5489 kg (12,100 lbs), large tire and rim options tailored for heavy loads, and exceptional ground clearance (284 mm or 11.2 inches). Its sizeable curb weight ensures stability, and the spacious crew cab accommodates passengers and equipment comfortably.
The Crew Cab configuration maximizes interior room, comfortably seating up to six passengers with two front bench seats or front bucket seats and a rear bench. The spacious cabin provides ample legroom and headroom, accommodating both work crews and families without sacrificing utility or comfort. The design also focuses on technology and convenience features to enhance driver experience.
