Reese Fifth Wheel Sidewinder Kingpin for Grand Design Solitude and 2022 Ford F-350


I just purchased a Grand Design Solitude with the attached specs. I wanted the Elite, but it appears that the loaded trailer weight will just breach the 16k mark. Would this system work and what else would I need? I also have a new F-350 that did not come with the puck system. Should I have the dealership add it or is there a better solution?


Helpful Expert Reply:

Your Grand Design Solitude will have a Lippert 1621 pin box, and since your trailer has a 16,600 lb GVWR, you'll need the 20k Goose Box, which is the following part number the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR.

Since your 2022 Ford F-350 did not come with the OEM prep package you'd need a custom fit rail kit like the Curt # C79BR which will minimize drilling and install much quicker than universal options. You'd then need a fixed hitch like the Curt A20 # C16140 which you would then also want the wedge part # C16991 to lock it to the Sidewinder.
