Cabinets are formed with a first chamber defined by end joined lengths of a first extrusion, a first chamber outer end closure and a first chamber inner end closure, which may include a second chamber defined by end joined lengths of a second extrusion edge interfitted with lengths of the first extrusion. Two or more cabinets may be combined to form a module. In a preferred construction adapted for use in fabricating a utility vehicle, such as a fire truck, a module includes two or more cabinets removably joined to a common walkway arranged to bridge across the cabinets.
