Hey Andy! The correct Blue Ox base plate kit for your 2026 Ford F-250 is the # BLU58ER. This will be compatible with your Blue Ox Avail # BX7420. Do you have the rest of your setup already? If not, you will need the following:

-Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267

-Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400

-Curt RVi Series Shadow 2 Flat Tow Brake System # RVI94FR

You may also need a high-low adapter to keep your setup level. I have attached a link below which explains how to measure. The Blue Ox base plate kit has a bracket height of 15-1/2" so you can use that along with your hitch measurement to find the right adapter.

Any big trips coming up with your motorhome once you get your new F-250 set up?

Hey Andy, how did things go getting the Blue Ox base plate set up on your F-250 with the Avail tow bar? It’d be great to hear if everything lined up as expected. Your update could make it easier for others planning a similar flat tow setup.
