When we ordered our (SOB) 5th wheel one of the options was a Rear Camera with Audio and we ordered the system. It comes on automatically when you got into reverse and also has a button on the dash that turns on the rear Camera while towing. I must say its awesome, and has a great wide angle view. The Freightliner also has a rear camera that works the same way. Our system is a hard wired system and you have to connect it from the FL to the 5th wheel. But now when some is behind the 5er you can see them and hear them make comments
???? All in all I highly recomend having a rear camera. GBY...
