A food truck is a large motorized vehicle (such as a van) or trailer, equipped to cook, prepare, serve, and/or sell food. Some, including ice cream trucks, sell frozen or prepackaged food; others have on-board kitchens and prepare food from scratch, or they heat up food that was prepared in a brick-and-mortar commercial kitchen. Sandwiches, hamburgers, french fries, and other regional fast food fare is common. By the early 2010s, amid the pop-up restaurant phenomenon, food trucks offering gourmet cuisine and a variety of specialties and ethnic menus became particularly popular. Food trucks may also sell cold beverages such as soda pop and water. Food trucks, along with food booths and food carts, are major components of the street food industry that serves an estimated 2.5 billion people every day. In the United States, the Texas chuckwagon is a precursor to the American food truck. In the later 1800s, herding cattle from the Southwest to markets in the North and East kept cowhands on the trail for months at a time. In 1866, the "father of the Texas Panhandle", Charles Goodnight, a Texas cattle rancher, fitted a sturdy old United States Army wagon with interior shelving and drawers, and stocked it with kitchenware, food and medical supplies. Food consisted of dried beans, coffee, cornmeal, greasy cloth-wrapped bacon, salt pork, beef, usually dried or salted, and other easy to preserve food stuffs. The wagon was also stocked with a water barrel and a sling to kindle wood to heat and cook food. Another early relative of the modern food truck is the lunch wagon, as conceived by food vendor Walter Scott in 1872. Scott cut windows in a small covered wagon, parked it in front of a newspaper office in Providence, Rhode Island, and sold sandwiches, pies and coffee to pressmen and journalists. By the 1880s, former lunch-counter boy, Thomas H. Buckley, was manufacturing lunch wagons in Worcester, Massachusetts. He introduced various models, like the Owl and the White House Cafe, with features that included sinks, refrigerators and cooking stoves, also colored windows and other ornamentation.
