Load measuring hitch assemblies are disclosed and described. In one embodiment, the assembly can include a body portion operable to facilitate coupling the load measuring hitch assembly to a tow vehicle. The assembly can also include at least one load cell operable to measure force in at least one measurement axis. Additionally, the assembly can include a ball portion having a ball operable to facilitate coupling the load measuring hitch assembly to a trailer. The ball portion and the body portion can be coupled to one another via the at least one load cell and a pin slot joint. The pin slot joint can provide relative motion between the ball portion and the body portion in a rotational degree of freedom about a first axis and a translational degree of freedom along a second axis. The first and second axes can be orthogonal to one another. The rotational and translational degrees of freedom between the ball portion and the body portion can facilitate transfer of a force to the at least one load cell in the at least one measurement axis, thereby facilitating determining a magnitude of at least one of a vertical or a horizontal force acting on the ball.
