Fitting the 2011 GMC Sierra 3500HD III Crew Cab Standard Box into a standard residential garage depends on garage dimensions. The truck is 6101 mm (240.3 inches) long, 2032 mm (79.9 inches) wide with mirrors open, and 1966 mm (77.4 inches) tall. Many standard residential garages are approximately 6 meters (20 feet) deep and 2.4 to 2.7 meters (8 to 9 feet) wide.

Compared to the previous generation (the GMT800 series), the 2011 GMC Sierra 3500HD III (GMT900 facelift) showed incremental size adjustments and refinements. The GMT900, including the III facelift, maintained a similar heavy-duty stance but optimized dimensions for better aerodynamics and interior space. While the overall length slightly increased or remained similar around 6.1 meters, improvements in weight distribution and payload capacities were notable, enhancing towing and hauling capabilities over the predecessor. Additionally, technological and safety upgrades made it a more modern heavy-duty truck.

In comparison with other heavy-duty pickups like the Ford F-350 Super Duty and RAM 3500 from the same era, the GMC Sierra 3500HD III's dimensions are competitive. Its length of 6101 mm (240.3 inches) and width of 2032 mm (79.9 inches) with mirrors open align closely with these rivals. Payload and towing capacities are also comparable, with subtle variations depending on configuration and drivetrain. The Sierra’s ride height and ground clearance are sufficient for off-road and work conditions, maintaining its position as a strong contender in the heavy-duty truck segment.

The Sierra 3500HD III Crew Cab Standard Box is designed to comfortably seat up to five or six passengers, depending on the seating configuration. Crew Cabs offer spacious rear seats with enough legroom and headroom for adult passengers on longer trips or workdays. Interior space is enhanced by the truck's large overall dimensions, making it practical for both family use and professional needs. The folding rear seats further increase cargo versatility by expanding the load floor inside the cab when necessary.

The 2011 GMC Sierra 3500HD III’s large footprint, substantial length (6101 mm / 240.3 inches), and width (2032 mm / 79.9 inches) contribute to its stability and power when towing or carrying heavy loads. Its curb weight from 2863 to 3345 kg ensures a solid road presence and durability. The ground clearance of 213 mm (8.4 inches) improves off-road capability and protects its undercarriage.
