Description: LIGHTWEIGHT RUST RESISTANT BODY ASSEMBLY BACKGROUND OF THE INVENTION The present invention relates to a body assembly for attachment to a truck chassis, and more particularly to a body assembly for attachment to a tow truck chassis. Trucks with body assemblies attached to their chassis have long been used. The body assemblies typically have storage compartments for tools and supplies. An example of a truck with an attached body assembly that is typical of the prior art is U.S. Patent No. 5,267,773 to Kalis, Jr. et al. (Kalis) . Kalis shows a body assembly that is formed from metal panels that are welded together and then bolted to the truck chassis. The body assemblies of the prior art, such as painted steel, suffer from a propensity to rust caused by the exposure of the metal panels to the elements particularly when used in colder climates and salt water climates. Body assemblies with welded metal panel construction have restricted styling design options and affecting repairs is difficult. Another drawback of the prior art is the need to have body assemblies that are unique to each truck chassis construction type, requiring the manufacturer and dealer to carry large inventories. None of the prior art body assembly approaches provide the advantages of providing a panel assembly for attachment to a truck chassis that is light weight and resistant to rust and providing a body assembly that can be adapted to multiple truck chassis construction types, along with improved styling options and simplified repair. SUMMARY OF THE INVENTION According to the invention, an improved adaptable body assembly having light weight and rust resistance is provided for attachment to a tow truck chassis. The improved body assembly comprises, a body unit, such as a left body unit and a right body unit. Each of the body units comprise a structural unit, and at least one exterior panel attached to the structural unit. The structural unit is constructed from a plurality of panels having flanges formed on at least one edge. In a preferred embodiment the panels are formed from aluminum. The structural unit includes a front panel and a back panel that are attached on opposite ends of a plurality of compartment panels. A top panel is attached to the top of the front panel, the back panel and the plurality of compartment panels, subassembly. The front panel, back panel, top panel and compartment panels are attached by adhesive disposed on the flanges. The panels form a structural unit defining a plurality of storage compartments. A plurality of exterior panels are attached to exterior surfaces of the structural unit. In a preferred embodiment the exterior panels are molded composite panels. An exterior panel top is attached to the top panel. An exterior front panel iε attached to the front panel, and an exterior rear panel taillight assembly is attached to a rear surface of the structural unit. The exterior composite panels are light weight and resistant to deterioration from exposure to the elements. The exterior composite panels protect the metal structural unit from exposure to the elements. The molded composite panels have improved styling capabilities over metal panels. In a preferred embodiment the molded composite panels are removably attached in order to allow for panel replacement in case of damage. The body unit has a plurality of storage compartments with doors providing access thereto. In a preferred embodiment the doors are formed from molded composite panels. In a preferred embodiment the front and rear panels of the structural unit are each provided with two wheel well cutouts. The structural unit can then be used for either single axle or tandem axle truck chassis. The front exterior panel is provided with either one wheel well cutout or two depending upon whether the truck chassis is single axle or tandem. If the truck chassis has a single axle the front exterior panel has one wheel well cut-out that corresponds to the single axle and covers the unused wheel well cut-out of the front panel. Further additional modular storage units can be disposed adjacent to a forward surface of the structural unit, increasing the length of the body assembly. This allows for a single construction type of structural unit to be used for single and tandem axle truck chassis with multiple chassis lengths cutting down on inventory required by the manufacturer and distributors. The present invention preserves the advantages of a body assembly for attachment to a tow truck having a plurality of storage compartments. In addition, it provides great new advantages not found in currently available body assemblies and overcomes many of the disadvantages associated with the known body assemblies. As pointed out in greater detail below, the present invention provides an improved body assembly that is light weight, resistant to rust and deterioration caused by exposure to the elements and adaptable to a variety of truck chassis types and sizes, with replaceable panels for simplified repair. The present invention may be adapted for use with tow trucks equipped with a variety of towing equipment as well as a wide variety of trucks and other vehicles in order to provide storage compartments.
