What was the name of Ford's first mass-produced truck?

Ford’s first mass-produced truck was the Ford Model TT, introduced in 1917.

The Model TT used the Model T’s basic mechanical design but added a longer wheelbase, heavier frame, and stronger rear axle for hauling. Ford initially sold it as a bare chassis, allowing buyers and independent body builders to add beds, boxes, tank bodies, buses, or other equipment. The first three examples were produced in 1917.

Unlike the passenger Model T, the TT was rated as a one-ton truck and was built for commercial work. Ford later offered a factory-built body, beginning in 1924, making the truck more convenient for customers who did not want to arrange their own coachwork. Production continued until 1928, when the Model AA replaced it.

The common mix-up is the Ford Model T: the TT was based on the Model T, but it was the dedicated truck variant. The Model AA was the successor, not the first Ford mass-produced truck, while the Model A was primarily a passenger-car name in this context.
