I have a 2010 F250. I removed the camera from the tailgate.....drilled one small hole in the center of the metal panel below the camper.....and remounted it there. Works just like it always did.
The camera has been there for 4 years now with no issues. I also enjoy the dotted lines that the factory Ford camera has.
Works just like factory....just slightly lower angle. You can see the guidance lines still work great....lined up perfectly with my ball hitch. The camera comes on only when the truck is in reverse....exactly like the factory set up.
When it comes time to sell the truck, I can remount the camera in the tailgate....put a small plastic plug in the hole.....and everything is back to factory.
Cost for this mod was zero. I had some old pieces of sheet metal laying around....and mounted the camera to one of them....I then used industrial strength velcro to mount the camera perfectly. It looks just like the factory mounted it there to begin with.
