A metal "A" frame structure capable, upon attachment, of towing a prefabricated building of, primarily, conventional frame construction. Metal "A" frame utilizes two identical leg members which attach to load distributing members that transmit the relatively heavy concentrated loads into the sides and front of the prefabricated building without introducing over stress. Interconnection of the various metal parts of the "A" frame is selectively accomplished by welding and bolting so that the "A" frame may be easily installed, removed and stored when not in use. The load distributing members which deliver the concentrated loads into the prefabricated building "box" may be adjusted in height, in the case of the front wall of the side walls in order to apply the loads at at the most structurally advantageous locations on the "box".
