The 2019 GMC Sierra 1500 V Regular Cab Long Box has a curb weight ranging from 2050 to 2146 kg (approximately 4519 to 4729 pounds), indicating the weight of the vehicle without passengers or cargo. Its maximum weight capacity ranges between 3084 and 3130 kg (around 6801 to 6900 pounds), which includes the vehicle's weight plus passengers, cargo, and towing capacity. This variance allows for different configurations and options affecting payload and towing abilities. Such weight specifications underline the vehicle's suitability for heavy-duty use, including hauling large loads and towing trailers, making it a dependable workhorse for both commercial and personal use.

The 2019 GMC Sierra 1500 V Regular Cab Long Box is equipped with versatile tire sizes depending on trim and usage, including options for 255/70 R17, 265/70 R17, and 265/65 R18 tires. Corresponding rim sizes are 8.0J x 17, 8.5J x 18, providing a balance of durability and performance. These tire and rim combinations enhance traction, off-road capability, and overall ride quality. The selection allows drivers to adapt the vehicle for varied conditions, from highway cruising to rugged terrain, ensuring stability, comfort, and safety across different driving environments.

The 'Long Box' designation of the 2019 GMC Sierra 1500 V Regular Cab refers to an extended cargo bed measuring approximately 2.4 meters (about 8 feet) in length, providing ample space for hauling large items, construction materials, heavy equipment, or recreational gear. This length maximizes cargo volume and supports applications requiring large, bulky loads. The extended bed length is a critical feature for users prioritizing maximum payload and utility, offering greater flexibility in transporting goods, whether for work or leisure purposes.

Considering the vehicle’s overall length of 5832 mm (229.5 inches) and width of 2063 mm (81.2 inches) with mirrors opened, the 2019 GMC Sierra 1500 V Regular Cab Long Box may pose challenges fitting into many standard residential garages. Typical single-car garages are about 6 meters (20 feet) deep and 3 meters (10 feet) wide, which is marginally adequate for length but potentially tight in width, especially with mirrors extended. Owners may need to fold mirrors if possible or consider a larger garage space to comfortably park without risking damage or difficulty maneuvering.

The 2019 GMC Sierra 1500 V, part of the GMTT1XX generation, brought refinements over its predecessor in terms of both dimensions and vehicle technology. While the overall size remained similar to ensure cargo and towing capabilities met customer expectations, the newer generation offered slight improvements in aerodynamics, weight optimization, and interior comfort features. For instance, there were incremental enhancements in curb weight management to improve fuel efficiency without compromising strength. The updated model also integrated advanced safety and infotainment technologies, enhancing the truck’s appeal as a modern, versatile vehicle designed to balance performance, utility, and driver experience compared to the previous generation.

Within the full-size pickup segment, the 2019 GMC Sierra 1500 V Regular Cab Long Box is competitive in size, with its 5832 mm (229.5 inches) length placing it among the longer trucks due to the extended bed. Compared to rivals like the Ford F-150 and Ram 1500, which offer similar bed lengths but different cabin configurations, the Sierra’s size emphasizes cargo hauling capability while maintaining a relatively wide stance at 2063 mm (81.2 inches) with mirrors out. This positioning makes it a practical choice for users requiring maximum cargo bed space without opting for crew cab variants. Additionally, its height of around 1920 mm (75.6 inches) provides good ground clearance while fitting within expected visual proportions for a rugged pickup truck.

The 2019 GMC Sierra 1500 V Regular Cab is designed with seating for two to three passengers depending on configuration, as it features a single-row cabin typical of Regular Cab trucks. This limits passenger capacity but maximizes the length available for the Long Box cargo area. The interior focuses on practical utility rather than extensive passenger comfort, providing durable materials and straightforward controls geared toward work use. Although not designed for family or multiple passenger transportation, the Regular Cab offers ample legroom and headroom for the driver and front passenger, ideal for those who prioritize cargo and towing capabilities over passenger space.

The maximum weight capacity of the 2019 GMC Sierra 1500 V Regular Cab Long Box ranges from 3084 to 3130 kg (6801 to 6900 pounds), which encompasses gross vehicle weight rating (GVWR). When it comes to towing capacity, depending on engine options and configurations, the Sierra 1500 V is capable of towing substantial loads typically ranging between 4000 to 6000 kg (8800 to 13200 pounds), making it a formidable truck for hauling trailers, boats, and heavy equipment. Payload capacity sits comfortably within industry expectations for a full-size pickup of this size, allowing it to carry heavy equipment and cargo reliably, aligning with the needs of commercial and recreational users.

The 2019 GMC Sierra 1500 V was offered with multiple engine options, including V6 and V8 gasoline engines, as well as a Duramax diesel variant in some trims. These engines were paired with advanced transmissions designed for improved performance and efficiency, such as 6-speed or 8-speed automatic gearboxes. The choice of powertrain influences the vehicle’s curb weight variations, which range from 2050 to 2146 kg (4519 to 4729 pounds), as more powerful engines and associated components typically add weight. These options allowed buyers to tailor the truck's performance and towing ability to their specific needs while balancing fuel economy and payload capacity.
