This report is a description of the data about the physical, operating performance, and market characteristics of light trucks for the model years 1955 through 1977, which is stored on tape in DOT/TSC DEC System 10 computer system. Information was collected from published and unpublished sources with extrapolation and correlations being made when raw data was not available. Vehicles are reported by model year and grouped by manufacturer, using production volume, model, body type, engine displacement, transmission and GVWR class attributes as criteria to select representative vehicle configurations. Models which are essentially duplicated by more than one division of a manufacturer--i.e., Chevrolet C-10 and GMC C-1S00--are represented by attributes of only one of the duplicate models. Production volume for both models is then combined. Characteristics are documented for vehicles representative of total U. S. sales of domestic and imported light trucks for the model years indicated.
