Kicked off by President Dwight D. Eisenhower in 1956, the Interstate Highway System was offering Americans increased access to recreational areas by the end of the '60s. America's truck culture changed too, rather than needing to meet the rigors of work or the joys of street cruising, drivers wanted trucks that could balance both tasks…and take them further afield. The Chevrolet C-10 answered a call for pulling trailers and cruising comfortably at Interstate speeds. Released in 1967, the C-10 Custom Sport Truck package brought luxury, car-like upgrades to pickups—a pioneering move.
