Tiffin uses 2 brands of Rear View systems. BOTH have the option of turning the individual cameras OFF from the menu programming. What will happen when you do this is, the Screen will go BLACK once you activate the Side Camera. I assume you still want to be able to see the rear camera, so the next item is what you need to do. The other way would be to cut the wire from the left turn signal switch input at the back of the monitor. What I would do is, cut that wire and run it thru a switch mounted on the dash to give me or others the easy option to turn it off or on. Also, I fail to see what advantage you think you get by NOT having it. If you do not like it, then don't look:h Doug
