I am looking into getting a wireless back up camera system. I see that the Voyager is highly recommend but it is only one camera on the rear cap. I would like to have a 3 camera system with one camera on the back cap and one on each side of the fifth wheel. It would be great if the side cameras activated with the turn signal but that is is not deal breaker. I have seen some 3 camera systems but they are all wired. I would like to get a wireless system. Does anybody know of a 3 camera wireless backup system that they would recommend?
