International Harvester began building trucks and pickups and later in 1907. In 1953 it added a truck-based people carrier, the Travelall. In the late 1950s it began to design a competitor for the two-door Jeep CJ 4x4. The 1961 model year Scout 80 made its debut in late 1960. Scouts began selling so well against Jeep, Ford jumped in with the Bronco and Chevrolet came out with the Blazer.
