A little over a month ago, I had a wireless camera installed on the TC.
The camera is mounted on the rear ladder and is wired into the license plate light. I can have it on all the time by just turning on the lights. I find very little distortion on the screen, overall a very good picture . It is a great improvement over the view out the small window in the camper door or the side mirrors. Complete view of the rear several lanes wide. We are planning on towing a car occasionally and I feel a lot better being able to check what's happening out back.
The camera I purchased was as follows:
Ultra Wireless Backup CCD
Camera and 7" LCD Receiver
Item#: 9901AV from www.4ucam.com
