• and
• a kingpin defining a body mounted with respect to the trailer, wherein the body is tapered such that the distance of the body at a first end is less than the distance of the body at an opposite second end;
• wherein the body is configured to engage with the slot of the hitch and is mounted with respect to the engagement surface of the head,
• wherein the vehicle and the trailer are in fluid and electrical communication when the kingpin is mounted with respect to the hitch.
