A Ford disconnects the circuit from its batteries to the 12V charge line when the ignition is off. Chevy and Dodge keep 12V on the charge line all the time. If you have a low trailer battery and are connected to either a Chevy or Dodge, then there is a chance the TV's batteries will be supplying 12V power to the RV. Too much 12V use may make starting the TV interesting.
