A corrosion-resistant utility body comprises a pair of body side storage compartment units adapted to be mounted along rear side portions of a truck chassis. Each storage compartment unit is comprised of a storage compartment assembly that comprises metal walls forming compartments that lead to separate side openings at the outside of the storage compartment assembly. The compartments can include a plurality of vertically spaced adjustable shelves for storing equipment, tools, supplies and the like. An outer one-piece face plate is fastened to outer surfaces of the storage compartment assembly. The one-piece face plate is comprised of metal and includes door openings aligned with each of the side openings of the storage compartment assembly. Door assemblies are connected to the one-piece face plate in alignment with the door openings. A utility vehicle includes a truck chassis, a cab mounted to a front portion of the chassis, and the present utility body mounted to a rear portion of the chassis. The utility body can be constructed using swage-type fasteners and so as to be weld-free. Also featured is a method of constructing the utility body.
