Installed on F350 with Backcountry OEV camper. Needed one extension cable, mounted rear camera high to see boat trailer's right side and second camera to see hitch. Suggest disconnects be added to be able to remove camper from truck. Needed the "flip image" control to help my brain understand the space behind me, it now looks just like the rear view mirror I was use to. Why not add a fourth camera option as a wireless camera?
