The earliest fire engines and fire trucks were hand operated but now gasoline and diesel engines do most of the work. Over the years dozens of manufacturers such as Ford, Chevrolet, Mack, American LaFrance, GMC, REO and Seagrave have produced fire engines and many other companies supply them with specialized accessories. This category is open to all types of fire trucks, pump trucks, hook-and-ladder trucks, EMT vans, etc.
