Abstract
An inverted bent bar weight distributing trailer hitch including a mono trunnion with a shank rotatably mounted therein. The mono trunnion is positioned on a base that contains a resistance member that engages the bottom portion of the trunnion. A biasing member is adjustably attached to the exterior of the base. By engaging the biasing member, the resistance member restricts the rotation of the mono trunnion about the shank.
