Thanks everyone for all your advise. I did get the Furrion 7 inch Observation today and have it installed. I was hoping the wire was live all the time. But I found out real quick the camera wire is live only when the running lights are turned on the truck. But, after thinking about this, it's really OK. In a way, it makes me feel better the camera shuts off when the lights go out, rather than running off the battery 24x7.
I have not taken the camper on the road yet, but we are going out again for another week-end jaunt to visit one of the local street fairs in a small town in Indiana (Denver, Indiana). So staying at Missassawana State Recreation area again. So, I'll have opportunity in about 4 days to test out the camera.
I got the kit with only the main back up camera. I saw the additional side and door cameras that you swap out with your running lights and add them in, but may wait for Christmas to get a set of them. I want to try out the main rear first for a while.
So once again, thanks everyone for all your suggestions and help. Happy camping and see you on the road!
