The 2015-2019 GMC Sierra 3500HD IV Crew Cab Standard Box has a length of 6083 mm (239.4 inches), a width of 2045 mm (80.5 inches) with mirrors opened, and a height ranging between 1985 mm to 1990 mm (78.1 to 78.3 inches). These dimensions make it a sizeable pickup truck designed for heavy-duty use while offering ample cabin space for passengers.

Given its considerable size, the GMC Sierra 3500HD IV Crew Cab Standard Box may find fitting into some standard residential garages challenging. With a width of 2045 mm (80.5 inches) including mirrors, and a length of 6083 mm (239.4 inches), standard garages, which typically measure around 2440 mm (96 inches) wide and 6100 mm (240 inches) deep, might accommodate it but with very tight margins especially width-wise. Additionally, the vehicle's height nearing 1990 mm (78.3 inches) is within typical garage door height clearance but owners should confirm exact garage dimensions and mirror folding ability before attempting to park inside.

The curb weight of the 2015-2019 GMC Sierra 3500HD IV Crew Cab Standard Box ranges between 2909 kg and 3424 kg (6416 lbs to 7551 lbs), reflecting its heavy-duty build. Its maximum weight capacity or Gross Vehicle Weight Rating (GVWR) ranges from 4763 kg to 5216 kg (10,497 lbs to 11,499 lbs). This high weight rating allows it to haul and tow heavy loads, making the Sierra 3500HD a true workhorse capable of handling demanding commercial and industrial tasks.

With a ride height or ground clearance ranging between 214 mm and 218 mm (8.4 inches to 8.6 inches), the GMC Sierra 3500HD IV Crew Cab Standard Box offers a capability that suits both on-road stability and moderate off-road terrain. This clearance helps the pickup manage obstacles like rocks or uneven surfaces without damage to the undercarriage, while still providing a lower center of gravity beneficial for heavy towing and improved road handling.

The rear cargo capacity with the seats folded down in the GMC Sierra 3500HD IV Crew Cab Standard Box is approximately 1728 liters (approximately 61 cubic feet). This volume demonstrates the truck's substantial interior versatility, enabling it to carry large amounts of cargo inside the cabin when needed, complementing the external bed's payload capabilities.

The standard rim sizes on this generation of the GMC Sierra 3500HD IV Crew Cab include 7.5J x 17, 8J x 17, and 8J x 18 inches. Tire sizes are typically 235/80 R17 and 265/70 R18, providing a balance between ride comfort, off-road capability, and the ability to support heavy loads. These specifications contribute to the truck's robust performance and handling characteristics.

Compared to its predecessor, the GMC Sierra 3500HD IV (2015-2019) increased in overall size and weight, reflecting advances in build quality and capability. It is longer and heavier, offering greater towing and payload capacities alongside enhanced interior space. These dimensional upgrades help it better meet the needs of commercial users and heavy-duty truck enthusiasts, although they may affect maneuverability in tight environments compared to earlier models.

The 2015-2019 GMC Sierra 3500HD IV competes strongly with comparable heavy-duty pickups such as the Ford F-350 Super Duty and Ram 3500. It generally offers similar or slightly larger exterior dimensions, robust towing capacities, and a premium interior finish typical of GMC’s Denali and SLT trims. While all three models excel in durability and power, the Sierra's slightly wider stance and higher curb weight translate to solid on-road stability, while the comparison in ride quality and user technology features often depends on specific trim levels and engine configurations.

The Crew Cab configuration of the GMC Sierra 3500HD IV prioritizes passenger comfort and interior space. It offers ample legroom and headroom for both front and rear passengers, making long journeys more comfortable especially for larger groups or families. The crew cab body style strikes a balance between passenger accommodation and cargo space with a standard box bed, making the truck versatile for both work and daily activities.

The Sierra 3500HD IV generation introduced a more modern and aggressive exterior design, focusing on improved aerodynamics and a higher-quality finish inside and out. Structural enhancements increased overall payload and towing capacities. Technology upgrades included better infotainment systems and safety features, making it more competitive in the heavy-duty truck market. The design also reflects GMC's premium positioning, with upgraded materials and a more refined cabin ambiance compared to earlier generations.
