I have an RV 760 with the BC 20 camera. It all works well. I did the install myself. Not too difficult if you are the DIY type
Image is fine from rear of my 40' long fiver to cab of truck.
I did need to buy the extension cable.
Camera can be used to view traffic while in motion. Camera does not see/work very well in the dark.
The BC-20 is a relatively cheap camera option if you own a Garmin GPS. I like the the fact I did not need an additional monitor in the cab. Having the ability to use the GPS screen as a back up camera and GPS display sealed the deal for me.
