Hi Jonathan!
The best flat tow wiring kit for your 2025 Ford F250 Platinum with LED taillights will be the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Way Coiled Adapter Cord # RM-15267. This will work with the LED lights and has all the ports needed to set up the braking system as well, though you will also need the Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 to keep your F250's brake signal from overriding the turn signal sent by your RV.
Do you already have the braking system and the rest of the flat towing components?

I don't have the braking system, but I am thinking I will go with the AirForce One Braking System. One other thing, can you look at the baseplates I would need? My 2025 F250 Platinum, is a tremor. I wanted the Roadmaster plates, but it seems those won't work. What would be the next best option (would prefer it be the kind that can be taken in and out like the Roadmaster one, so it's not as visible when not in use). Thoughts? Do I need the cable that will charge the battery on the F250 as well?
