Want to hook up a backup camera
 

I have the backup camera installed on my 2011 3500, and it works great but I also have a Arctic Fox camper and I would like to install a camera on it that will work with the installed screen.
When I remove the tail gate I have to plug up the ports, what I really want is a camera that will work with my onboard system.

Anyone got an Idea??

I have the "mygig lock pick" and you can add cameras, toggle between the different cameras and it is viewed on the factory screen. I have had a problem with mine giving a blank screen when in reverse and the reverse camera does not work with the engine brake on (I just turn mine off when needed). I have not given Coastal Electronic Technologies a call yet to fix the blank screen issue.
