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.
As such, the size of squad trucks is varying, and can be classified into three distinct categories.
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.
