Abstract: The invention is a multipurpose adaptor box for a dump truck designed to fit into the dump truck box of a dump truck. The adaptor box has an exterior surface that surrounds an interior chamber so that the box defines essentially a bottom and four sides with an open top. The rear side of the adaptor box (i.e. the tailgate) includes a door means for providing access to the interior chamber. The door is swing mounted on hinges to the exterior surface of the adaptor box and has an opening passing through it that is designed to allow a leaf blower system to be attached to the adaptor box so that lawn refuse can easily be loaded into the adaptor box when desired. A removable opening cover, capable of being mounted to the door, is provided for covering the opening when it is not needed. The open top of the adaptor box is defined by the top edges of the side walls. A grate is used to cover the top opening to the adaptor box.
