Ram Van Guide: ProMaster Specs, Cargo and Upfits
People searching for a Dodge Ram Van today are usually looking at the Ram ProMaster. This guide explains the name change, then walks through roof heights, wheelbases, cargo volume, payload, towing, cab features and the conversion market.
Why the Name Causes Confusion
The full-size van sold under the Ram name today is the ProMaster, not a Dodge. Ram was split off as its own truck and van brand in 2010, so vehicles that once wore a Dodge badge now wear a Ram one. The original Dodge Ram Van, the B-series, was a body-on-frame rear-drive van whose production run ended in the early 2000s, replaced first by the Sprinter-based Dodge Sprinter and later by the ProMaster. So a search for a new Dodge Ram Van is almost always a search for the current ProMaster. Both names describe the same place in the lineup: a full-size work van sold as cargo, passenger and chassis variants.
Front-Wheel Drive and What It Changes
The ProMaster is front-wheel drive, which is unusual among full-size vans and is the single biggest difference from rear-drive rivals. With no driveshaft or rear differential running under the load area, the floor sits lower, typically around twenty-one inches from the ground. That means a shorter step up, less lifting when loading heavy items, and more usable height inside for a given roof height. Front drive also puts engine weight over the driven wheels, which tends to help traction on wet roads and light snow when the cargo bay is empty, a common condition for delivery work. The trade-offs are a lower towing ceiling and a turning behaviour some drivers need a few days to learn.
Roof Heights, Wheelbases and Cargo Volume
The ProMaster is sold in several body combinations rather than one size. Wheelbase choices have generally spanned roughly 118, 136 and 159 inches, with the longest body adding an extended rear overhang behind the 159-inch wheelbase. Roof height comes in low and high versions, with the high roof giving well over six feet of interior standing height for most adults. Cargo volume scales accordingly, from roughly 260 cubic feet at the small end to around 530 cubic feet in the longest high-roof body. Interior width between the wheel housings is wide enough to lay standard sheet goods and most pallets flat, which is a practical reason trades buyers choose it.
Payload, Towing and Drivetrain
Payload ratings on recent ProMaster cargo models commonly land in the 3,500 to 4,200 pound range depending on body length, roof and equipment, so the useful figure is always the one on the door-jamb label of the specific van, not a brochure maximum. Towing is typically rated around 5,100 pounds, which is lower than some rear-drive competitors and reflects the front-drive layout. Power has come from a gasoline V6 in most years, paired with an automatic transmission; a turbodiesel four was offered in earlier model years in North America. Always subtract passengers, upfit weight and fuel from payload before planning a load.
Cargo, Passenger and Chassis Configurations
Three broad body types cover most needs:
- Cargo van: the volume seller, sold with a solid bulkhead or window options, sliding side door on one or both sides, and rear doors that swing wide.
- Passenger or window van: seating rows fitted from the factory or by a second-stage builder, used for shuttles, crew transport and accessible conversions.
- Cutaway and chassis cab: a cab and frame with no cargo body, supplied to upfitters who build box bodies, service bodies, refrigerated boxes and small motorhomes.
Rear doors on the cargo van open to a wide angle, often 260 degrees, so they can be folded flat against the body at a loading dock.
Conversions, Upfits and Camper Builds
The ProMaster has become a favourite base for camper van conversions, and the reasons are structural rather than sentimental. The side walls are close to vertical, so cabinets and a bed platform sit flush instead of being scribed to a curve. The body is wide enough that many builders can sleep crosswise without a flare, which saves length. The low floor keeps the finished interior height reasonable, and the flat floor simplifies subfloor and plumbing runs. For commercial work, shelving, racking, partitions, refrigeration and electrical upfits are widely available off the shelf. Factory upfitter packages, pre-wired auxiliary power and body-builder documentation make second-stage work more predictable.
Choosing One: What to Weigh Up
If you came here searching for a Dodge Ram Van, the vehicle to compare is the Ram ProMaster, and the honest comparison is against the Ford Transit and Mercedes-Benz Sprinter. Start with the load you actually carry: measure the longest and tallest item, then pick wheelbase and roof from that, not from the headline cargo figure. Check payload on the door label of the exact van. Weigh low floor height and square walls against the lower towing rating. Then look at the boring factors that decide long-term cost: parts availability, local service capacity, how quickly an upfitter can turn the build around, and whether door openings suit your loading method. Availability and specification vary by market and model year, so confirm details locally.
