2023 Ram ProMaster 3500 Cargo High Roof Extended – Ultimate Workspace on WheelsStep into major capability with this 2023 Ram ProMaster 3500 Cargo in the High Roof Extended configuration — designed for seamless up-fitting, high-volume hauling, and professional-grade performance. With one of the most spacious interiors in its class, this van is tailored for businesses that demand both room and reliability.
Under the hood, the 3500 carries a robust 3.6-litre V6 engine producing around 276 horsepower and 250 lb-ft of torque, paired with a 9-speed automatic transmission and front-wheel-drive layout for a lower load floor and excellent maneuverability. With the extended wheelbase and high roof, you’re looking at cargo lengths up to approximately 13 feet, interior standing height near 77 inches (High Roof) or more in the Super High Roof upgrade, and floor widths that make pallet-placement and full builds straightforward.
The cargo area is built for serious work: with maximum cargo volumes surpassing 460 cubic feet in this configuration, along with payload ratings roughly in the 4,400-to-4,700 lb range depending on exact spec. Dual rear swing-out doors, a wide sliding side door, up-fitter-friendly tie-downs and nearly vertical side walls all combine to make this van a flexible platform for trades, mobile service units, delivery fleets or custom conversions.
