The chuckwagon is attributed to Charles Goodnight, a Texas rancher, who introduced the concept in 1866. Cattlemen herded cattle in parts of the country that did not have railroads which meant they needed to be fed on the road for months at a time. Goodnight modified the Studebaker wagon, a durable army-surplus wagon, added a "chuck box" to the back of the wagon with drawers and shelves for storage space and a hinged lid to provide a flat cooking surface. A water barrel was also attached to the wagon and canvas was hung underneath to carry firewood. A wagon box was used to store cooking supplies and cowboys' personal items. Chuckwagon food typically included easy-to-preserve items like beans and salted meats, coffee, and sourdough biscuits. Food would also be gathered en route. There was no fresh fruit, vegetables, or eggs available and meat was not fresh unless an animal was injured during the run and therefore had to be killed. The meat they ate was greasy cloth-wrapped bacon, salt pork, and beef, usually dried, salted or smoked. The wagon was also stocked with a water barrel and a sling to kindle wood to heat and cook food.
