I had ran out of propane for fridge and fridge automatically switched over to 12v that night so when go to start truck....dead, not even a click. So now I make sure to set fridge to gas only and remove plug from truck. I was going to check gas left in tank on wkend but ran out Thursday night/Fri morning. Had to buy 2 truck batteries for truck(RAM 3500) but was able to get camper batteries to hold a charge. I'm in process of making a battery disconnect So i dont have to keep climbing under to remove cable. I have solar but doesn't work at night. Also don't want to just disconnect power from truck as it may become an emergency power source.
