Question:
Can you tell me what the difference is between RP87FR and RP39FR? It would be installed on a 2021 F350 Super duty.

Expert Reply:
The two parts you mentioned are both the same Reese Elite Series Under-Bed Rail and Installation Kit that fit your 2021 Ford F-350 Super Duty, giving you the ability to pull a gooseneck trailer with a gooseneck ball or use a 5th wheel hitch in the puck system.
The only difference is that we have one listed as a 5th wheel install kit and the other as a gooseneck hitch, but the # RP39FR and # RP87FR are the exact same, the Reese Elite Series Underbed Kit.
So you can just get the less expensive option, and use the Ball for Reese Elite Series # RP19311 for a gooseneck trailer and the Reese M5 5th Wheel Trailer Hitch # RP30922 for a 5th wheel trailer.
Finally, for a wiring harness on your F-350 the best option is the Curt 5th Wheel/Gooseneck Custom Wiring Harness for Aluminum Beds # C57010.
