The Removable Gooseneck (RGN) trailer has a detachable front end that turns the trailer into a ramp. Past the detachable section of the trailer, RGNs are equipped with a double drop formation that lends the payload an extra amount of height, usually around 12 extra inches.
The variable nature of the RGN trailer allows it to accommodate cargo that is more difficult for less flexible trailers. Referred to as a “detach”, the RGN is ideal for transporting less than standard cargo, equipment that is longer, taller, or otherwise a non-normal size.
