I do the same as Ron (GStream 40) and also have not had any leaks or busted pipes in over 30 years. Back in the day of home made converted buses we used copper for the water lines with pressure systems if you had a leak what a mess when you pressurised the system!
I know I'm old probably most of you don't remember pressure systems no water pumps just a small compressor to make the water flow no plastic tanks either most tanks were galvanized . (Boy am I dating my self) Good luck winterising folks
