Me too. Draining the whole system is just so easy in my new fifth wheel. But I do suck up RV antifreeze into the fresh water tank and use the 12 volt pump to run it thru the water lines until they're spitting pink. And I drain the hot water tank too.
Once you get used to doing the system this way, it's a very fast and easy proposition.
