If you leave some in the black tank and are connected to shore power, can you simply turn on the tank heater to keep it from freezing? We’re having a week of lows in the teens but plan on camping again soon. I drained and flushed all (hwh, lines, etc). The pump plumbing also had to be disconnected - about qt. of water was still in it and it’s tubing. What a pain. The heater would work for the fresh tank too. I know my way is not the same as you guys in cold country that put the RV to sleep for the winter.
