Preventing Battery Drain

Parking our Pod while connected to the tow vehicle is draining the battery on our truck. We have nothing on or running in the trailer? Should we disconnect the trailer brake cable?

Thanks!👍🏼 What about the fridge? What setting should it be on when not using?

Completely agree with GlueGuy. Running the frig on battery does not keep it as cold as the propane option or 110-120VAC. I ran the frig on battery when traveling for almost a year and could not ever get the temp below 42-43 even on mild days before I got smarter through reading many of these messages. I even went to the trouble of putting two pancake fans in the mechanical section to increase the air flow over the heat exchanger. Once ran the battery on the TV down to the point I needed a jump start. I was not a happy camper that morning.

Are the propane refrigerator police really going to go into your Pod to check to see if the fridge is turned on with propane while you're filling up at your local Pilot or Flying J?  

Besides that, most of the time you're going to spend not more than about 10 minutes refueling, max.  You could turn the valve off for the time you're at the pump, then turn it back on as you leave.  If you have a long ferry ride or something the issue could be a problem, but there unless you're going to be in transit on the boat more than an hour, there  is enough insulation and carry over cold that it probably wouldn't make much difference anyway; unless, of course you're going from Rihad to the port of Dubai.
