Does anyone REALLY think that's good for their health?
Even if you rinse it out, does anyone REALLY believe that they get it all
out, that it doesn't stick in the pores of the plastic?
Please, someone enlighten me where I am wrong about this.

Bill,

Where do you live?  Have you ever changed a cracked, water
spewing pump or faucet?

Yes, RV antifreeze is used commonly (it's sold at every FLAPS
in northern Utah).  It does pollute the system.  Most RV owners
put T valves entering and exiting their water heaters to protect
those tanks.

Otherwise, it's simply flushed (as many a dozen times) to remove
as much of the chemical as possible.

Next time you Sunbelter's come up here to ski, rent a car and think
about what it takes to have one perform through the winter.  Then
think about what you would do with your Westy when the temps
get below O degrees F.

BTW  I'm getting about 50/50 replies of shocked amazement, and
those who say just drain tank and lines or drain and add
antifreeze.

I can tell you an inline pump (78 Westy) freezes at about 20 F.
I'll call the RV dealer about submersible pumps.  Their reply is
utterly predictable as they both sell antifreeze and winterize
vehicles.

Appreciate all the replies.

Keep to the High Road
