1. A weight measuring hitch ball assembly, comprising:
a hitch ball having a ball and a lower portion;
a body portion defining a hitch ball opening that slidably receives the lower portion of the hitch ball;
a load measurement device operably associated with the body portion and the hitch ball to determine a magnitude of a force acting on the hitch ball; and
a hitch mount interface, configured to interface with an attachment structure that facilitates coupling the weight measuring hitch ball assembly to a tow vehicle,
wherein the hitch mount interface comprises a coupling feature operable to facilitate securing the weight measuring hitch ball assembly to the attachment structure,
wherein the coupling feature comprises a movable ball operable to extend into a groove in the attachment structure to secure the weight measuring hitch ball assembly to the attachment structure and to retract from the groove to facilitate removal of the weight measuring hitch ball assembly from the attachment structure.
