There was plenty of skilled labor for body building since wagon making was an important Indiana business and across the country more and more firms were discarding the horse and wagon in favor of the motor truck. Selling their interest in the glass business to Owens, Joseph and Robert joined Ray in establishing a factory in Evansville, Indiana, to build truck bodies for mounting on passenger car chassis. By 1920 an expanded line of Graham Brothers trucks and buses were being manufactured, using Continental, Weideley and Dodge engines. A customer, the Grahams felt, should not have to go elsewhere for his truck's body, so they built complete vehicles, offering a variety of bodies designed to meet the specialized needs of various industries.
