if so all you need to do is run a wire from the plug to your battery
the factory systems isolate the RV battery from the TV system when the key is off so the TV's battery doesn't discharge
here is a diagram of what came w/ both my F-350 and my Jeep Cherokee factory towing packages
the "12v Power" is the one
BON CHANCE

I would check ebay
Consider the length of the trip and your demand needs.
You need to decide how large a battery and what charging
rate is needed to provide it.
