heavy - duty
the design of squad trucks varies, depending on the geography and need in any given area. areas with rough terrain or snow usually have squad trucks with four-wheel drive, jake brake, locking differentials, hydraulic brakes, and aggressive tires. often, squads trucks are old ambulances that have been stripped to carry the necessary tools and equipment needed for an extrication, however, rescue squads or fire departments with a high amount of funding often purchase custom trucks that are more elaborate and functional squad trucks. as such, the size of squad trucks is varying, and can be classified into three distinct categories. class i, or light duty squad trucks are the smallest, and usually the cheapest squad trucks. they can range from a converted ambulance or chevy suburban type truck, to custom built trucks on ford f550 chassis. class ii, or medium duty squad trucks are substantially bigger in both the physical size of the truck and its weight. medium duty squad trucks can range from smaller fire engines specifically designed for extrications to international truck cabs and chassis. class iii, or heavy duty squad trucks are usually the dimensions of a full sized fire engine and often include more exotic tools such as cascade systems and plasma torches.
