"By 1968, Chevrolet began focusing on providing the C10 with a smoother ride, more room in the cab and some creature comforts that were once reserved only for passenger cars. The truck featured smoother lines, as Chevy marketed it as a second family vehicle. The 115-inch wheelbase version measured 186.75 inches in length, with a front tread width of 63.1 inches and a rear tread width of 61.1 inches. The 127-inch wheelbase model measured 206.25 inches in length, with the same front and rear track dimensions."
