What is the best practice for leaving the propane tank on and then being unattended? For example, you set up camp or set up at home, turn on propane, plug in to electric power, etc. use whatever you use, etc. then leave for several hours. Is it better (safer) to turn off the propane if the trailer will be unoccupied more than 6 hours? 8 hours? X hours?
Maybe I worry too much,
but I thought what happens when we are gone and the gas alarm goes off, no one will be there to hear it and turn off the gas at the tank.
