2020 Chevrolet Silverado 3500 HD IV (T1XX) Double Cab Long Bed Dimensions, Size & Specs

With the rear seats folded up, the cargo space inside the Silverado 3500 HD IV Double Cab Long Bed is quite generous, offering a luggage capacity of approximately 2364 liters (83.5 cubic feet). This large volume is crucial for users who require space for tools, gear, or supplies inside the cab. Additionally, given its pickup truck configuration with a long bed, the truck bed itself (separate from the interior cab space) provides even more extensive cargo hauling capability. The combination of interior cargo flexibility and an expansive truck bed supports both commercial users and personal owners who demand heavy-duty utility and spacious storage options.

The Silverado 3500 HD IV Double Cab Long Bed has a curb weight ranging from 3034 kg to 3713 kg (6689 to 8184 pounds), depending on specific trim levels, equipment, and drivetrain configurations. This weight reflects the sturdiness and robustness of the vehicle, built to endure heavy loads and tough work conditions. The maximum weight it can handle (gross vehicle weight rating, GVWR) ranges from 5035 kg to 6350 kg (11,103 to 13,999 pounds), illustrating its capacity to carry heavy cargo, tow substantial trailers, or transport heavy equipment. These numbers confirm why the Silverado 3500 HD is categorized as a heavy-duty pickup truck, suitable for demanding work environments.

Fitting the Silverado 3500 HD IV Double Cab Long Bed into a standard residential garage can be challenging due to its large size. With a length of 6514 mm (256.3 inches), a width of up to 2457 mm (96.7 inches) when mirrors are open, and a height reaching up to 2054 mm (80.9 inches), this truck often exceeds the dimensions of many typical garage spaces. Most standard garages are approximately 6 meters (about 20 feet) deep and 2.4 to 3 meters (8 to 10 feet) wide, which may be insufficient to comfortably house this vehicle without folding mirrors and significant clearance adjustments. Owners with oversized trucks like the Silverado 3500 HD often require custom or larger garages designed for heavy-duty pickups or opt for alternative parking arrangements such as driveways or covered carports.

The ground clearance of the Chevrolet Silverado 3500 HD IV Double Cab Long Bed ranges between 264 mm and 284 mm (approximately 10.4 to 11.2 inches), depending on the trim or suspension setup. This relatively high ride height helps the truck navigate off-road conditions, obstacles, and rough terrain without damaging the undercarriage. It also improves the vehicle's ability to ford through shallow water and drive over uneven surfaces commonly encountered in construction sites or rural areas. This ground clearance is typical for heavy-duty pickups, balancing heavy load capacity with off-road capability, ensuring the Silverado 3500 HD is both durable and versatile for diverse driving environments.

The Chevrolet Silverado 3500 HD IV Double Cab Long Bed offers multiple rim size options ranging from 17 inches to 20 inches, including 7.5J x 17, 8J x 18, 8.5J x 18.5, and 8.5J x 20. Corresponding tire sizes encompass 265/70 R17, 245/75 R17, 275/70 R18, 275/65 R20, and 265/70 R18. Larger rims and tires tend to provide enhanced traction, better handling, and improved stability on various terrains, including highways and off-road surfaces. The versatility in rim and tire options allows buyers to optimize their truck based on intended use, whether for heavy hauling, towing, or more off-road-oriented driving. These options also impact ride comfort and vehicle aesthetics, balancing between ruggedness and drivability.

Compared to its predecessor generation, the 2020 Silverado 3500 HD IV Double Cab Long Bed shows a clear evolution in both size and capability. While exact dimension changes can vary by model year and trim, the T1XX generation Silverado generally offers more modern styling, improved aerodynamics, and better interior space utilization. The length of 6514 mm (256.3 inches) and wider stance with mirrors open up to 2457 mm (96.7 inches) reflects a design focus on maximizing cargo and towing potential. Additionally, improvements in chassis, suspension, and technology enhance ride comfort and towing safety. In short, the 2020 generation delivers a more refined, powerful, and spacious heavy-duty pickup experience compared to the previous Silverado 3500 HD.

The Chevrolet Silverado 3500 HD IV Double Cab Long Bed is competitively sized within the heavy-duty pickup segment. Trucks like the Ford F-350 Super Duty and Ram 3500 Crew Cab Long Bed have comparable dimensions, often slightly varying in length around 6.1 to 6.5 meters (approximately 240 to 256 inches) and width near 2.1 to 2.5 meters (82 to 98 inches) with mirrors unfolded. What sets the Silverado apart is its range of configurations and robust build, offering multiple tire and rim choices, a generous maximum weight capacity, and high ground clearance. When choosing among these heavy-duty pickups, Silverado’s dimension and weight characteristics strike a balance between maneuverability and maximum hauling capability, appealing to those who need serious work capacity without excessive bulk.

The double cab configuration of the 2020 Chevrolet Silverado 3500 HD IV provides ample interior space for passengers and cargo. While not as spacious as crew cabs, the double cab still offers a well-sized rear seating area suitable for passengers or additional cargo inside the cabin. With rear seats that fold up, the Silverado delivers a flexible cargo area inside the cabin totaling approximately 2364 liters (83.5 cubic feet), accommodating tools, equipment, or personal belongings securely and out of weather exposure. Features inside the cabin focus on durability and functionality, with materials designed to withstand rigorous use typical in heavy-duty trucks, while also integrating modern technology and convenience options for comfort during long drives or workdays.

The curb weight of the Silverado 3500 HD IV ranges from 3034 kg to 3713 kg (6689 to 8184 pounds), reflecting its heavy-duty construction aimed at durability and load capacity. While a heavier curb weight can negatively impact fuel efficiency due to the increased energy needed to move the vehicle, it also contributes to a stable, solid road feel and the ability to tow or haul substantial loads. The maximum weight capacity between 5035 kg and 6350 kg (11,103 to 13,999 pounds) further highlights the truck’s workhorse nature. Prospective buyers should expect moderate fuel consumption relative to lighter vehicles but gain exceptional towing and payload capacities. Many owners prioritize these performance benefits over fuel economy since the Silverado 3500 HD is optimized for demanding jobs and rugged conditions.
