Horace and John Dodge reluctantly agreed to develop a commercial vehicle in 1917 after their sales associates lobbied for a work truck that could be sold to small businesses that made deliveries of fruit, beer, and other goods. The result was a vehicle based on the first Dodge passenger car. The vehicle eventually became the 1920 Screenside half-ton vehicle that is considered the predecessor of Dodge's light-duty pickup trucks. Photos by Paul Clinton.
