Ram ProMaster stands apart in the full-size van class with front-wheel drive, a boxy cargo shape, and the widest available interior between the wheel wells. The 2026 lineup offers three roof heights (66, 77, and 86 inches) and four cargo lengths up to roughly 13 feet, with a 3.6L Pentastar V6 driving up to 4,820 lbs of payload.

Ram Professional is Stellantis's commercial-focused program backing the ProMaster with dedicated BusinessLink dealers, fleet incentives, and commercial financing. HVAC and plumbing contractors can spec Tradesman, SLT, and SLT+ trims, with an available rear heating/AC prep package.

For HVAC fleets prioritizing low step-in height, wide cargo box, and a lower price point than Sprinter or Transit, ProMaster is frequently the TCO winner.
