As the market evolved, Dodge realized that a bigger and stronger van line would be needed in the future. The B Series was introduced for 1971 offering both car-like comfort in its Sportsman passenger line or expansive room for gear and materials in its Tradesman cargo line. A chassis cab version was also offered for use with bigger cargo boxes or flatbeds. Like the trucks, Chrysler's dire financial straits of the late 1970s precluded any major updates for the vans for many years. Rebadged as the Ram Van and Ram Wagon for 1981, this old design carried on for 33 years with little more than cosmetic and safety updates all the way to 2003.
