Hi John!

For your 2023 For F350, I recommend getting the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Way Coiled Adapter Cord # RM-15267. This is a bit of work to get installed, but it's American made and is the best option for your truck.

Do you already have the other components to flat tow your F350?

@John Good call with the 10k set up. Definitely one of those "If it's worth doing, it's worth overdoing" kind of things. Do you have a braking system? If not, the Curt RVi Series Shadow 2 Flat Tow Brake System - Wireless Monitor - Proportional - Fixed # RVI94FR is one the our newer braking systems for us, but we are hearing very good things about it. Another one that's a little bit of work for the install, but it also works very well and is pretty easy to use and set up.
