On display at the 2003 National Convention from Ralph Ratcliffe was this articulated Mack off-road dump combination. This big Mack uses the same power unit as the Mack M-65 dump truck Ralph has produced as a very limited production model (Photo Gallery 14). The model is built entirely of resin parts Ralph cast from mold masters he machined from ABS plastic and structural shapes. Also shown in Photo Galleries 79 and 82.
