Compatibility of Reese Goose Box With Recessed Gooseneck Ball on Flat Bed Truck


I have a f450 with a flatbed and recessed ball. can I still use this? my other truck is a 21 f350 8ft bed and It should be fine with that truck correct?


Expert Reply:

If the recessed well that the gooseneck ball sits in is at least 15 x 15 inches square and no greater than 5 inches deep, then yes you can use the # RP94720 Reese Goose Ball 5th wheel to gooseneck hitch adapter. The # RP94720 model you'd looked at is compatible with Lippert 1621, 1621HD, and 0719 OEM pin boxes and has a 20K capacity.

We also offer the # RP94716-61301, compatible with Lippert 0115, 1116 and 1716 with a 16K capacity and the # RP94716 which replaces the Lippert 0719, 1621 and 1621HD as well as the Fabex PB-600 Series with a 16K capacity.

The Goose Box will work just fine on truck with a standard bed (as opposed to a flat bed).

If your OEM pin box isn't on the list mentioned above, you'll be better off using Demco Recon 5th wheel hitch, part # DM8550046. The Recon will require that the recessed well that the gooseneck hitch is set in measures greater than 22 inches square. The top of the gooseneck ball can't be any lower than 13/16 below the level of the truck bed.
