The 2020-2023 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed pickup truck has impressive overall dimensions suited for heavy-duty tasks and comfortable driving. It measures 6352 mm (approximately 250 inches or 20.8 feet) in length, making it a substantial vehicle on the road. The width with mirrors opened is 2079 mm (about 81.8 inches or 6.8 feet), ensuring the truck provides a wide stance for stability but requires attention during tight maneuvers. The height stands at 2027 mm (approximately 79.8 inches or 6.65 feet), contributing to its commanding presence and spacious cabin. These dimensions place the Sierra 2500HD in the heavy-duty full-size pickup category, providing both rugged performance and ample interior space.
The curb weight of the 2020-2023 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed ranges between 2963 kg to 3502 kg (6529 to 7719 pounds), depending on the configuration and equipment chosen. The maximum weight, which includes the gross vehicle weight rating (GVWR), spans from 4604 kg to 5058 kg (10,154 to 11,146 pounds), reflecting the truck's capacity to carry heavy loads including passengers, cargo, and trailer tongue weight. This heavy curb weight and high maximum allowable weight contribute to its excellent towing and payload capacities, making it a robust workhorse ideal for demanding towing and hauling tasks. However, this weight also means the vehicle demands strong braking systems, durable suspension, and substantial powertrain components to maintain performance and safety.
The GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed from 2020 to 2023 features a generous ride height or ground clearance of 257 mm (approximately 10.1 inches). This level of ground clearance is beneficial for off-road performance, allowing the vehicle to navigate rough terrain, obstacles, and uneven surfaces without damaging the undercarriage. It also aids in providing better water fording capability and reduces the risk of getting stuck on uneven paths. Combined with its heavy-duty build, this makes the Sierra 2500HD well-suited for off-roading, work sites, and other demanding environments where clearance and ruggedness are essential.
The 2020-2023 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed is equipped with several rim size options to meet various performance and aesthetic needs. These include 17-inch, 18-inch, and 20-inch rim diameters, with rim widths ranging from 7.5J to 8.5J. The tires available correspond to these rim sizes and include options like 265/70 R17, 245/75 R17, 265/70 R18, 275/70 R18, and 265/60 R20. Larger rims and tires typically improve handling and road grip, especially on highways and paved roads, while slightly smaller tires may enhance off-road traction and comfort. Moreover, tire size influences load ratings and ride quality, making tire choice important depending on how the truck will be used — whether for heavy hauling, off-road adventures, or everyday driving.
Given the overall dimensions of the 2020-2023 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed, fitting this truck into a standard residential garage can be challenging. This pickup measures 6352 mm (about 20.8 feet) in length, 2079 mm (approximately 6.8 feet) wide with mirrors extended, and about 2027 mm (6.65 feet) tall. Standard single-car garages typically have an interior length near 5500-6100 mm (18-20 feet) and widths of about 2740 mm (9 feet), meaning the truck is longer than many standard garage depths but slim enough to fit width-wise if mirrors are folded. Therefore, while the truck may fit, garage doors large enough to accommodate the width with mirrors extended are required, and careful maneuvering is necessary to avoid damage. Owners of the Sierra 2500HD should check garage dimensions or consider larger garages or parking solutions.
The 5th generation GMC Sierra 2500HD (GMTT1XX), produced from 2020 to 2023, demonstrates some notable changes compared to its predecessor, the 4th generation. While both maintain the heavy-duty full-size pickup profile, the 5th generation generally offers a longer overall length at 6352 mm (about 250 inches) compared to the 4th gen’s typical lengths around 6000-6200 mm (236-244 inches). This increase in length provides more spacious interiors and improved cargo bed options. Width including mirrors has also seen a slight increase to 2079 mm (81.8 inches), enhancing road presence and stability. Height remains similar but varies based on suspension packages. The 5th gen also benefits from updated technology, improved materials, and refined aerodynamic styling, making it a more modern and capable truck overall. It builds on the strengths of the 4th gen while improving comfort, capacity, and capability.
When compared to similar heavy-duty pickup trucks such as the Ford F-250 Super Duty, RAM 2500, and Chevrolet Silverado 2500HD, the 2020-2023 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed fits well within the expected size range for this vehicle class. Its length of 6352 mm (250 inches), width of 2079 mm (81.8 inches) with mirrors open, and height of 2027 mm (79.8 inches) are comparable to these rivals, although slight variations exist depending on configuration and cab styles. For instance, the Ford F-250 Super Duty and Chevrolet Silverado 2500HD have lengths ranging from approximately 6100 mm to 6350 mm, so the Sierra is generally on the longer side. Widths with mirrors extended are similarly broad for all models, often nearing or surpassing 2 meters to accommodate mirrors and ensure visibility. These dimensions highlight the Sierra 2500HD as a competitive option in the heavy-duty segment, balancing cargo space, cabin comfort, and maneuverability.
The GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed from 2020 to 2023 is designed to provide comfortable seating and a practical cargo bed. As a Crew Cab, it offers spacious seating for up to five or six passengers depending on the configuration, with ample legroom and headroom for both front and rear occupants. Crew Cabs are known for their family-friendly interiors, providing ease of entry and exit and versatile storage. The Standard Bed option typically measures approximately 1524 mm (60 inches or 5 feet) in length, offering a balance between passenger space and cargo capacity. This bed length is shorter than the Long Bed variants but ideal for maneuverability while still offering enough room for hauling tools, equipment, or recreational gear. Together with versatile interior features, these dimensions cater to users wanting heavy-duty capability combined with passenger comfort.
The 257 mm (10.1 inches) ride height of the 2020-2023 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed, combined with its curb weight ranging between 2963 kg and 3502 kg (6529 to 7719 pounds), results in a vehicle built with a focus on capability rather than fuel economy. The higher ride height elevates the truck’s center of gravity, which can slightly affect handling characteristics, especially when cornering, but it significantly boosts ground clearance necessary for off-road and hauling scenarios. The heavy curb weight contributes to increased rolling resistance and inertia, which typically results in greater fuel consumption compared to lighter vehicles. Modern powertrains and aerodynamic improvements help mitigate this effect, but drivers can expect the fuel efficiency to be lower than lighter pickups or SUVs. Despite this, the truck delivers a commanding driving experience suited for demanding workloads, towing, and rugged terrain.
For the 2020-2023 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Standard Bed, tire and rim combinations are selected based on intended use, balancing factors like durability, performance, load capacity, and ride comfort. The available rim sizes range from 17 inches to 20 inches in diameter, with widths from 7.5J to 8.5J. Recommended tire sizes include 265/70 R17, 245/75 R17, 265/70 R18, 265/60 R20, and 275/70 R18. For heavy-duty towing and off-road use, the 17-inch and 18-inch rims fitted with tires like 265/70 R17 or 275/70 R18 are ideal, as they offer larger sidewalls to absorb impacts and improve durability over rough terrain. The 20-inch rim with 265/60 R20 tires is better suited for highway driving and lighter-duty usage, providing enhanced handling and a smoother feel on paved roads. Selecting the right combination depends on driver priorities, but these options provide flexibility across various applications.
