With a length of 6330 mm (249.2 inches) and a width of 2436 mm (95.9 inches) including mirrors, the 2007 GMC Sierra 3500HD Extended Cab Long Box is quite large. Most standard single-car garages have lengths about 6100 mm (20 feet) and widths around 3050 mm (10 feet). While width might be manageable if mirrors are folded, the length likely exceeds standard garage depth, making it a tight or impossible fit in many single garages without modifications.

The 2007 GMC Sierra 3500HD III Extended Cab Long Box competes closely with trucks like the Ford F-350 Super Duty and the Ram 3500 in the same model year bracket. Its length of 6330 mm (249.2 inches) and width of 2436 mm (95.9 inches) are generally comparable or slightly larger depending on the competitor's configuration. It stands out with its combination of heavy maximum weight capacity, substantial ground clearance, and spacious extended cab, offering competitive cargo and towing capacity for work and commercial use.
With mirrors opened, the 2007 GMC Sierra 3500HD III Extended Cab Long Box has a width of 2436 mm (95.9 inches). This extra width is significant when maneuvering in tight parking spaces or narrow lanes. Drivers need to be cautious in such environments and possibly fold mirrors when stationary to avoid damage. The wider stance improves stability on the road but requires mindful spatial planning in urban or congested areas.
The height of the 2007 GMC Sierra 3500HD III Extended Cab Long Box varies slightly between 1927 mm to 1931 mm (75.8 to 76.0 inches). These differences can result from varying suspension setups, tire sizes, and optional equipment such as roof-mounted accessories or clearance lights.
