Wireless Camera Recommendations

I installed a two camera system from Rear View Safety. I tried two Iball wireless and had interference with both. They said it was due to Bluetooth, Onstar, Sirius, etc. Don't know for sure. Anyway, I got the hard wired system and have no interference. I put one camera on the truck with a license plate mount for the hitch with grid. The second I mounted on the spare tire cover of my Flagstaff TT. Only hole I drilled was in the cover of the spare. It comes with quick disconnect from TT to Truck. Seven inch monitor mounted under the radio on the dash. I had it installed at a truck accessories dealer to the ignition/run switch. It comes on automatically on the hitch and then I toggle to the rear camera. I love being able to see what is coming up behind me and how fast they are traveling. Takes the worry out of changing lanes. I can also see much better when backing the TT. I would highly recommend having two. It is so easy to back under the hitch every time. They are infrared as well and is really good for hitching up in the wee hours of the AM before the sun comes up. The wife loves not having to guide me to the hitch as well.
