That fuse tap will work perfectly. shouldn`t need anything more than a 15 amp fuse. good luck! I have mine hooked up so I can turn it on and off with the switch on the monitor, it doesn`t come on in reverse.
The rear view camera is no different than a rear view mirror. I don`t think anyone with a rear view camera (including me) is constantly staring at the monitor. it is used as a rear view mirror. the side view mirrors give a good view down the sides of the camper and the road. the camera will give a good view behind the trailer.
