The Studebaker 2R is a series of light- and medium-duty trucks built by the Studebaker Corporation from April 1948 until the end of 1953. For the 1954 model year, after a light redesign, the line was renamed 3R and built for an additional eight months. Studebaker had worked on a still born post-war design earlier, called the R, and so the new truck was given the 2R designation. The most distinctive characteristic of Studebaker 2R/3R trucks is the cab, which remained in production with minor changes through the 1959 model year. A one-piece windshield arrived in February 1954 (becoming the 3R series) and a larger rear window arrived in 1955 for the succeeding E-series.
