I have reently purchased a 2005 23' Class B+ motorhome and love it, but it didn't come with a rear view camera. Any suggestions as to a good one to buy? I also was wondering if there is a device that would transmit image wirelessly via Bluetooth. I have an Ipad and of course a smart phone. I saw one that had GPS built in as well, but can't remember who it was. Any input will be graciously accepted. Happy Holidays!
