Unlike Ram pickups with an open cargo bed, the Promaster is a fully boxed truck allowing owners to haul more cargo and keep everything protected against the elements or prying eyes. The rear cargo area of the long-wheelbase configuration can fit more than 13,000 litres. Available exclusively as a commercial van, the Promaster comes standard with a 3.6-litre V6 engine that sends 280 horsepower and 260 pound-feet of torque to the front wheels.
