The fifth wheel was invented by the American inventor and mechanic, J. W. Sturtevant, in the late 19th century. His design allowed for a more stable and flexible connection between trucks and trailers, revolutionizing the transportation of goods. The fifth wheel mechanism has since evolved but remains a critical component in modern trucking and trailer designs.

When you get it to where you want it, lock the fifth wheel. Pull forward or backwards slightly to ensure the fifth wheel is locked in place.

not sure, but probably due to spare wheel(fifth wheel) used to be kept in pickup bed, which is where fifth wheel hitch goes. ==Not quite == In the days of horse-drawn wagons, the fifth wheel was a wheel placed horizontally over the front axle of a large wagon to facilitate turning. Basically, it allowed the front axle to pivot. Today, the coupler of a tractor-trailer truck is called the fifth wheel, mostly because it's round (somewhat) and is vaguely reminiscent of the wagon's fifth wheel (which much more closely resembled the wagon's other four wheels).
