  You need to install an isolation relay on your TV.  This will prevent battery drain from your TV battery.  Another option is to just disconnect the 7 pin from the TV.  Our Sienna charge line remains live when the ignition is off, so when we stop for lunch when on the road, we just disconnect the 7 pin.  We probably don’t even need to do that because our ARB sips power.  Just need to remember to reconnect.

  Thank you @Sharon_is_SAM ..  is this done by the car or the RV dealer?   (and thank you for removing my duplicate post! I just moved to my desktop to see if I could somehow but couldn't figure it out)  :-)

  I think an aftermarket auto electronics installer might do it.  Not sure if an auto dealer would do it.  Anybody else know!

  Why would you want to leave it plugged into the vehicle?

  I wired a toggle switch on my dash to cut off the power to the 7 pin when I stop.

  @Bclarke:  Either make it a point not to forget...OR the one time you do forget, will be your last and once you have recharged your TV battery, you'll never do it again! Thats what separates us from the apes...we learn from our mistakes(oh, and something about the thumbs...)!

  You need not feel foolish. All apes have opposable thumbs. Most every lifeform learns from mistakes.  Some of us just learn faster.

  @Bclarke - if you do disconnect, just clip a reminder to reconnect to the steering wheel.  Can’t avoid seeing that!

  I would definitely take it to an auto repair shop and have the isolator installed. Automatic things make it easier on us and makes life more enjoyable. I would go to a local shop that specializes in automotive electronics. (Alternator replacement, etc.)

  I understand worrying about plugging back in
  I have no skills with electrical systems 
  
  Just use old fashion reminders
  Started with little sticky note then small noodle piece on steering wheel
  
  Helps with wheel lock since moving with it on scares me more

  You don't need to feel foolish. If you don't mind diddling with your trailer pigtail (and the associated reminders) every time you stop for sandwich or a pee break, then by all means that is a good solution for you. Personally, that would just aggravate me--I like your original idea of getting an isolation relay installed!
