Abstract
A pin box assembly having a column connected to a skid plate with an upper and lower surface. A kingpin is affixed to and extends from the skid plate. The skid plate is restrained from movement with respect to the column, and the column is for being connected to a towable RV. A strain gauge may be mounted to an upper surface of the skid plate. As an alternative to mounting the strain gauge to the skid plate, the strain gauge may be mounted to the column of the pin box. The strain gauges in the aforementioned locations measure strain as the weight of a towable RV is placed upon a fifth wheel hitch.
