B&W Companion RVK3710 with turning point pin box. This setup allows me to turn around at the top of my driveway, just have to fix the stones. I also like the turning point as it makes for faster(tighter) turns in the campground.
I learned a lot the hard way with wireless transmitters and receivers when I setup rear and Sideview cameras on my 5th wheel to my Titan xd. If I wouldn't have had this option on the chevy, I would have put in a replacement rear view mirror with full view monitor and wireless transmitter and receiver. Would have been clean and automatic always on with lights.
I have ios, they have had the truck since Monday night and are waiting on a new intellihaul 2.0 unit. The techs at echomaster(AKA amp research) think the unit is bad. I pull a 32' fifth wheel and the wireless camera works reasonably. I need to get an extension cable for the antenna to eliminate the delay. I added the front view camera to help with tight maneuvers.
