Re: [A/S] tank capacities
John,
The only thing you have to do to "winterize" you fresh water storage
tank is to drain it.
DO NOT put antifreeze in it. While RV antifreeze won't kill you it
doesn't taste good. The design of the tank leaves some water in the tank
unless you open up the bottom drain plug which is hidden up inside the
tank enclosure. Any antifreeze you would put in it will evaporate into
the rather rough interior of the tank and will be revived next year when
you fill it. And then you would end up spending hours draining and
refilling to get the taste out of the water. Not good.
Just drain it and let it dry out naturally, don't put anything in it to
"protect" it. It doesn't need it.
