cheeze1 - Sounds like it might be less expensive for you. Do I dare ask what has happened to the previous tail lights? :) Several topics have been posted about the value of a backup camera. Some have recommended the wireless since you don't have to run the cabling between the camera and the monitor. Much cheaper than a dented fender etc. Just checked ebay and found 278 listings for backup cameras. Almost all of them were selling for under $200. I like the ones that have a camera mounted on the top bolts of the rear license plate. The source of power is the backup light circuit. Image transmitted wireless to the front monitor which obtains power from the cigarette lighter or hardwired.
I had thought about replacing the bulbs in the interior of our unit with LED bulbs, but don't know if there really is enough of an advantage. The coach battery would hold charge longer, but price of bulbs are high.
