An easy way to determine if you've disconnected the battery from most everything except the propane detector is ... If you can pull out the red lever ... battery is disconnected ... If you can't pull out the red lever ... battery is connected.
Ok so when you are traveling do you have the battery "disconnect" in the off or on position?
I travel with the "disconnect" in the "on" position so I have power to the fridge. I run with the fridge on propane but even so it requires a 12 volt source to operate.
