Ok so disconnecting the 12 volt is a bad idea, got it. And Since someone asked, I don't have running water for a dumb reason, the house I live next to does not have a hose long enough to reach the RV to fill the tank. But I have a key to the house so I can go in there for bathroom, laundry, washing dishes etc.. so life is not so bad.. until it rains... Ya know how some old RVs have a crank you turn on the ceiling that extends an antenna on the roof? You guessed it.. drip, drip, drip from where the crank is. I have a can of Henry roof sealer a friend gave me but no ladder to get up there but thats a minor thing I guess. I will try and get that done before the next rain.
I never use the stove for cooking because I live right next to a 99 cent store and they have lots of microwaveable stuff to cook. I will try and use the stove for heat as little as possible. I hope the LPG test thingie is reading right and the propane tank is actually 2/3 full, it looks like it holds about 15 gallons.
