Advantage Plus! Hydraulic Detachable Gooseneck (HDG) trailer features a new “arched” design of the gooseneck, providing ample truck-frame clearance. It also offers a five-position gooseneck door adjustment that allows for an 8-inch range of king-pin-height settings. New heavy-duty pullout front outriggers are built right into the frame and provide extra strength at the pivot point. Spring-loaded, stainless-steel latches can be turned and locked open. In addition, many optional features now come standard, including covered knuckle trough in rear deck, covered boom trough in wheel area, third lift axle, adjustable ride-height control, LED lights, sealed plug-and-play electrical system, and more.
