I have a 2016 F-350 Lariat. I want to install a second backup camera (high mount) to see my fifth wheel hitch when hooking up. It will be located either near or in the third brake light. I really do not want to add another display or change the OEM display. My question; is there any way to add a second camera input the the OEM head unit? Or can I use the A/V inputs and disable the OEM Backup Camera when I want to use the high mount.

 

If you have a front view camera input, you may be able to use it for your second cameara.
Or, throw a switch between the two, on the rear view connection.

 

OEM cameras are costly but see no reason you couldn't add one in.

Part GC3Z19G490B, prices vary on eBay.
