Probably number 1 tip, if the unit isn’t hooked to shore power, disconnect the battery. All newer units have phantom electrical loads, stereo memory, CO/propane detector and so on. This will totally kill the battery within two weeks or less. A dead battery can take several days to fully recharge and it puts a heavy load on your converter if you are using the unit while a heavy charge is taking place, possibly leading to a converter failure. It also greatly shortens the life of the battery.
