The Dodge B series (later the Dodge Ram van) is a range of full-size vans that were produced by Chrysler Corporation from the 1971 to 2003 model years. Replacing the Dodge A100, the Ram Van relocated the drivetrain and front axle forward of the passenger compartment. Alongside cargo and passenger versions (under multiple nameplates), the model line was also initially offered as a cutaway van chassis. Through 32 years of production (making it among the longest-lived platforms in American automotive history), the Chrysler B-platform van was produced under three distinct generations, with much of the exterior and chassis underpinnings remaining unchanged for its entire production. During the 1970s, versions the model range were rebadged for Fargo Trucks and for the Plymouth brand (marking the debut of the Plymouth Voyager). For its entire production run, Chrysler produced B-platform vans at the now-demolished Pillette Road Truck Assembly plant in Windsor, Ontario, Canada; prior to 1980, the model line was produced at Saint Louis North Assembly (Fenton, Missouri). In 2003, the Dodge Sprinter (a rebranding of its Mercedes-Benz namesake) was introduced, replacing the B-series van entirely from 2004 to 2006. From 2014 onward, the Dodge Ram Van has been replaced by the Ram ProMaster (a rebranding of the Fiat Ducato). Model overview Built on the B platform (later AB), the Dodge full-size vans entered production for the 1971 model year. Using a one-welded-piece "Uniframe" design, the platform was lighter and stronger, giving a lower cargo floor than previous American designs. While at the expense of noise, vibration, and harshness (NVH), the resulting lower center of gravity improved handling versus competing products with full frames. Produced over three distinct generations, the B-series van utilized the majority of body sheetmetal from 1971 to 2003. Alongside passenger and cargo vans, the model line also served as a basis for cutaway chassis during the 1970s, serving both commercial markets and as a basis for recreational vehicles. Though popular in the latter market, Chrysler Corporation would end production of that design as a consequence of their late 1970s financial difficulties. The relatively limited changes for the model line across its production made the Dodge Ram van popular with fleet buyers, service companies, and upbuilders because of the compatibility of components across various model years. In two size extremes to the market segment, Dodge was the first American manufacturer to popularize extended-length passenger vans, with the 1971 "Maxiwagon" introducing
