Class 325
The Class 325 was designed for all around fire protection in isolated areas with little or no water supply.  It was the most widely
used fire truck in theater of operations and thousands were built.  It was built on the Dodge, Chevrolet and Ford 1 1/2 ton 4x2
and the Chevrolet 4x4 chassis.  Bodies were manufactured by most of the major fire apparatus manufactures.  The truck was
equipped with a front mounted 300 gpm pump and a 300 gal. water tank.  Duel hose reels, each carrying 150 ft. of 1 in. hose
were mounted below the platform type body. The Class 325 was used to combat structural and brush fires at stateside and
overseas areas and could be used in lieu of the Class 300 as needed.

The Class 300 fire truck was supplied primarily to Army Camps that might be subject to forest or
brush fires.  It was built on the Chevrolet and Ford 4x2 chassis and the Chevrolet 4x4 chassis.  The
bodies were manufactured by Darley, Central and American Fire apparatus.  The truck was
equipped with a 300 gpm front mounted centrifugal pump and carried a 250 gal water tank.  Duel
hose lines each carrying 150 ft of 1 in hose were mounted atop the hose body.  The unit was
equipped with standard brush firefighting tools and the hose body could carry 1000 ft of 1 1/2 in
hose.
The Class 335 had it's beginnings in 1943 when a hybrid fire truck was created by the members of the 1208th Engineer Fire
Fighting Platoon in Algiers, North Africa.  An 800 gallon water tank was mounted on the standard GM CCKW 2 1/2 ton cargo truck
and the pump, piping, tools, hose and other fire fighting equipment from a Class 325 was added and proved quite successful.

The Corps of Engineers adapted this idea and contracted with General Detroit in March 1945 to build 50 conversion kits to modify
other CCKWs into fire fighting vehicles, this kit became the Class 335.  This kit conversion was especially designed to convert the
standard 2 1/2 ton, 6x6 into a satisfactory piece of fire fighting equipment.  The truck body was constructed of steel and included a
640 gallon water tank, together with supports, wood slat hose bed, tool compartment, running boards, a portion of the hooks and
brackets for mounting tools and all bolts, nuts, washers and screws needed for mounting the body on the chassis.  Included in the
kit was the rear step assembly and frame extension for mounting a 300 gpm centrifugal fire pump on the front end of the chassis.  
The conversion kit was intended for installation in the field and all fire fighting equipment would be removed from a Class 325 and
used to equip the converted vehicle.  These vehicles retained their original Army serial numbers as seen in the following pictures.
