The RAM ProMaster 3500 is a cargo van that offers key updates to a variant sold by Fiat in Europe. It has roughly twice as much cargo space as some of its competitors. Perhaps more important for van buyers, the rear doors are nearly the same size as the interior, which can help with loading bulky objects. Drivers will appreciate spacious interior room by the standards of its class. Engines are competitive in terms of both power and fuel economy, and it handles well in tight spaces to boot.
