Take a look at Westin Automotive’s (westinautomotive.com) “Max Winch Tray”. Part No. for a 2020 F-250 is 46-23905, if I read the website correctly. Anyway, that is the winch tray I used to mount a Warn VR-10 on my 2017 F-150. The tray mounts directly to the truck frame via existing threaded holes. It was very quick and easy to mount. And you don’t have to remove the stock bumper, just two rectangular pop-out black plastic piece, located just beneath the bumper (for optional Ford driving lights?). Also, I was able to easily remove the two Ford tow hooks and remount them on the Westin tray.
This winch tray has been on my 2017 for 3 yrs and there have been no issues.
