    RW-1630 VARYING FRONT RAILGEAR CONFIGURATIONS Due to the numerous variations between chassis, DMF has designed several different mounting configurations to supply our customers with the perfect fit for their application. These configurations fall into three main categories as listed below. Each of these categories, though similar, requires varying installation procedures.
