Can someone explain the difference between a "goose-neck (gn)" and a 5th wheel please? Reading the various posts, it appears that they are 2 different hitch systems. What the U.S. members refer to as bumper pull is all I am familiar with.
A fifth wheel is just what it says. A smaller version of a semi tractor connector. A gooseneck is a general term for a type of trailer but is generally regarded to mean a 2 5/16" ball in the bed of a truck that a socket on the trailer drops onto. The fifth wheel has a king pin that slides into the jaws and latches.
