During the First World War, the company provided the Model 16 3/4-ton truck, and modified its production to provide 1-ton troop carriers and aviation support vehicles, and by 1918, more than 90 percent of GMC truck production was for military use. In 1916, a GMC truck crossed the country from Seattle to New York City in thirty days, and in 1926, a 2-ton GMC truck was driven from New York to San Francisco in five days and 30 minutes. GMC maintained three manufacturing locations in Pontiac, Michigan, Oakland, California, and St. All General Motors truck production was consolidated at the former Rapid Motor Plant 1 in Pontiac, Michigan. In 1912 the Rapid and Reliance names were dropped in favor of "GMC". In 1911 General Motors formed the "General Motors Truck Company" and folded Rapid and "Reliance Motor Car Company" (another early commercial vehicle manufacturer that Durant had acquired in 1908) into it. Durant gained control of Rapid Motor Vehicle Company and made it a subsidiary of his General Motors Company. Roots to the GMC brand can be traced to 1900, when the "Grabowsky Motor Company" was established by brothers Max (1874-1946) and Morris Grabowsky, in Detroit, and renamed Rapid Motor Vehicle Company in 1902 when the brothers moved operations to Pontiac, Michigan.
