Mercedes-Benz Sprinter vs. Ram ProMaster: An Honest Comparison

The ProMaster is front-wheel drive with a much lower, wider load floor and a lower purchase price. The Sprinter offers diesel, higher payload and towing ceilings, taller stand-up roof heights and stronger resale. Choose the ProMaster if you hand-load heavy items all day or move pallets. Choose the Sprinter if you run high annual miles, tow, or work standing up inside the van.

Where the Ram ProMaster genuinely wins

Load floor height, and it is not close. The ProMaster sits at 21 inches, the lowest in the class, because front-wheel drive removes the driveshaft. If your crew lifts heavy items dozens of times a day, that difference compounds over a career.

Cargo width. 75 inches wall to wall and 56 inches between the wheel wells, against roughly 51 inches for the Sprinter. That is the difference between fitting a pallet or sheet goods crosswise and not.

Purchase price. The ProMaster starts around $47,655. A comparable Sprinter starts higher — the 2026 full-size Sprinter is listed near $53,680.

Service network breadth. There are more Ram dealers than Mercedes-Benz commercial dealers nationally. For a fleet running long routes, that matters.

Where the Sprinter wins

Payload and towing ceilings. The Sprinter tops out at 6,812 lbs payload and 7,500 lbs towing but that is the 4500 series. A Sprinter 2500 Cargo carries 4,211 lbs, and the ProMaster actually out-tows it at 6,910 lbs. Compare the configurations you are actually buying, not the headline maximums.

Diesel. The ProMaster is gas-only in the U.S. Sprinter diesel returns roughly 22 to 26 mpg on long highway routes, which changes cost per mile for high-mileage operators.

Roof height. Sprinter high-roof configurations allow most adults to stand fully upright. For mobile service businesses working inside the van, this is often the deciding factor.

Longevity. Sprinter diesels routinely exceed 300,000 miles with maintenance on schedule.

Resale and upfit ecosystem. Sprinters hold value well, helped by camper conversion demand, and have the deepest catalogue of purpose-built upfit hardware.

Which is cheaper to own?

Purchase price favours the ProMaster, clearly. Total cost depends on mileage. Below moderate annual miles the lower price usually wins outright; at high mileage, diesel efficiency and stronger resale close and eventually reverse the gap.

Tell us your real annual mileage and we will run the arithmetic honestly. If the ProMaster wins at your numbers, we would rather tell you than sell you the wrong van.

Which has more cargo space?

Comparable at similar lengths. The ProMaster’s squarer walls use it more efficiently; the Sprinter offers more vertical room.

Which is better for a camper conversion?

Sprinter, by a wide margin roof height, drivetrain options, and a far larger conversion parts market. See our conversion buying guide.
