Question:
Hello, I have a 2020 Ford F350 SRW with the short bed. It does NOT have the factory prep package nor the the welded-on brackets. I would like to purchase the Reese RP39FR. Do I just need the Reese RP27FR to be able to mount it, or is there anything else I need?

Hey Caleb! The Reese Under-Bed Gooseneck Trailer Hitch # RP39FR comes with the outer frame brackets and hardware for installation. If you do not have any inner frame brackets (listed in the diagram below as #18 with the note *factory) you will also need the # RP27FR. Once this is installed you will be able to use 5th wheel hitches for the OEM prep package like the PullRite SuperGlide # PUL73RR.
