2020 GMC Sierra 2500HD V (GMTT1XX) Crew Cab Long Bed Dimensions, Size & Specs

The curb weight of the 2020-2023 GMC Sierra 2500HD V Crew Cab Long Bed ranges from 3009 kg to 3577 kg (approximately 6633 to 7885 pounds), depending on the variation and optional equipment. This weight reflects the truck's robust construction and heavy-duty capabilities. Heavier weight helps with stability and towing capacity but can impact fuel efficiency and maneuverability. The truck's suspension and powertrain are engineered to manage this weight effectively, balancing power and control for heavy hauling and off-road performance.

The 'Long Bed' designation in the 2020-2023 GMC Sierra 2500HD V Crew Cab means it comes with an extended cargo bed length compared to standard or short-bed variants. While specific bed length metrics aren’t listed in the given data, traditionally, long beds on heavy-duty trucks like this are approximately 2440 mm (96 inches) long. This extended bed length allows for hauling larger and longer loads, making the Sierra 2500HD ideal for contractors, landscapers, and those who require significant cargo capacity without compromising passenger space in the crew cab.

The total width of the GMC Sierra 2500HD V Crew Cab Long Bed with mirrors extended is 2079 mm (81.8 inches). This width is considerably wider than the vehicle’s body width, which means drivers need to be cautious when navigating narrow parking spaces, garage entrances, or crowded urban roads. The extended mirror width can make tight maneuvers more challenging, and it's important to take mirror width into account when parking or passing through narrow passages to prevent collisions or scraping.

The GMC Sierra 2500HD V Crew Cab Long Bed offers a ground clearance of 256 mm (10.1 inches). This elevated ride height is beneficial for off-road driving and uneven terrain, as it allows the truck to clear obstacles like rocks, ruts, and debris without damaging the undercarriage. Additionally, higher ground clearance helps in tackling deep snow, mud, or water crossings, making it a suitable choice for work sites or recreational off-road activities where rugged conditions are common.

Standard residential garages typically measure around 2440 mm (8 feet) wide by 4880 mm (16 feet) deep with a height of about 2130-2440 mm (7-8 feet).

Therefore, it generally will not fit comfortably in a standard single-car garage, particularly if you open the mirrors or include additional equipment.
