A structural cross frame connector is described having a multipurpose system of attachment. The device has two main forms one with a vertical offset and one without this vertical offset. The central portion has an arch by which weight is distributed accordingly. The connectors have a a group of pass through holes whereby a pass through rod is attached thereto using fasteners. Various structural members can be attached to the pass through rod using pass right and left pass through cavities typically used as structural support members and a central pass through cavity typically used as a hitching station. Leaf springs are also mountable on pass through rods and freely operate on another connector right and left pass through cavity for use as a suspension system.
