Question:
Is it possible to use this with a gooseneck ball? My king pin box hits my bed rail.

Expert Reply:
A Sidewinder like # RP61420 cannot be adapted to work with a gooseneck trailer hitch ball. What you would need to use is a Goose Box like # RP94622 for Lippert 0719, 1621 and 1621HD or Fabex PB-600 Series pin boxes. Or, we have # RP94622-61301 for Lippert 0115, 1116 and 1716 pin boxes.
We have other adapters for towing a 5th wheel trailer with a gooseneck hitch. I have included a link to an FAQ article that covers the options.
You can also try a taller ball and lower the pin box or coupler on the trailer if possible for greater clearance.
