Abstract: A frame assembly for supporting and mounting a box compartment over and around a flat bed of a flatbed tow truck is described. The frame assembly includes a frame attached to a chassis of a flatbed tow truck. The frame includes at least one left and at least one right side support beams, at least one left and at least one right horizontal connection beams, two or more left side and two or more right side vertical support beams, at least two cross-beams, and at least one vertical connection beam. One or more of the at least two cross-beams is connected to the chassis and is further connected at each of its ends to the left and right side support beams. Each vertical connection beam is connected to either the left or right horizontal connection beam and is oriented generally vertically for attachment of a box compartment to the frame.
