The new ford hitch has an underbed structure that accepts a gooseneck ball or a 5th wheel upper structure. It is primarily compatible with Reese signature series upper structures. The upper structures are to be co-branded with Reese. The holes are provided in the bed prior to painting, so no corrosion issues (per auto show display). The heights of the mounting pads are flush with the top of the bed beads. Current Reese aftermarket pads stick up above the bed beads by about 1/4 to 1/2".
