  • Will this hitch fit a 2022 ford f350 with a factory installed gooseneck

  • I currently have a 1999 F-350 4x4 SD CC LWB with a toolbox system that just reached the height of the bed rails. What I would like to do is to mount your hitch onto 2 rails that fastened to the bed rails so that I can have the option of moving a 5th wheel rig. This would be infrequent, so the system would be bolted together. Do you have any suggestions, positive or negative, to give me?

    This is just the base for the 5th wheel hitch. Do you have the head assembly?
