About ProMaster
The Ram ProMaster is the FCA/Stellantis answer to Sprinter and Transit. Italian-designed (Fiat Ducato platform), front-wheel drive, with the widest interior of any van in the segment — a 4 ft wide bed fits sideways without truncating storage. The FWD layout drops the floor lower than Sprinter or Transit (no driveshaft hump), making conversions roomier.

When ProMaster wins
Trips where interior width matters more than ground clearance. Tall renters (6'4" + ceiling). Trips on paved roads in regions with snow but not extreme off-road need. Budget #vanlife trips (lowest premium).
When ProMaster loses
Off-pavement trips (FWD struggles on loose surfaces — no AWD option). Trips in mountainous terrain where engine breaking on long descents matters (FWD trans heats faster). Trips above 8,000 ft (V6 loses power; non-turbo loses more than turbo).
What official guides don't tell you
PickRV — first-hand context.
FWD ProMaster goes where you can drag a sedan — gravel forest service roads are fine, snowed-over high passes are not.
ProMaster step-in height is the lowest of the three big vans (about 16 inches vs 18-20 for Sprinter/Transit) — best for older renters or accessibility.
ProMaster electrical layout (vs Sprinter) typically gives easier solar wiring access — battery box under driver's seat is reachable.
Pentastar V6 fuel economy is 16-18 mpg in conversion trim — middle of the pack.
FCA dealer parts are widely available; the Italian DNA (Fiat Ducato shared parts in Europe) means import parts are sometimes faster to source than American specs.
