If the owner blows out the water system with compressed air according to recommended procedure, there is no use for putting antifreeze anywhere but in the traps of the drain pipes. I don't care what the water tastes like in the traps.
What happens when you get water collecting in a low point? You cannot get 100% of the water out with compressed air!

I think it sounds interesting, from a chemical perspective. We're the type of family that eats organic foods, avoids artificial stuff, takes herbs, etc., and the idea of drinking water from lines that have had antifreeze in them is icky to me,
If you use any commercial prepared foods, toothpaste, cosmetics, and even many medicines, odds are you've been ingesting the common food additive propylene glycol. Propylene glycol also happens to be the primary ingredient in most RV antifreeze.
What a fantastic way to transport booze across the border! Never though of something like that before!
But to answer the OP's post: nope, never heard of anyone actually doing this.
I put it in a Mercedes windshield washer fluid container when I was in West Berlin years ago. Even flushed everything out really well first. Could not get any windshield de-icer fluid and the Vodka was very cheap at the Class 6 store!
“All journeys have secret destinations of which the traveler is unaware.”
"I think I've heard that people who live where it gets cold can't just blow out the lines and have to use antifreeze everywhere, so it's something I'd want to research better if we ever lived somewhere I had to do that. It's my goal to never live somewhere that cold, though."
That just is not true. Many of us who live in "cold country" use air pressure to blow out the lines in the RV, just like we do with our underground sprinklers!
In reply to the OP, yes, an alcohol based anti-freeze will work just fine. It is doubtful that much evaporation will occur during cold weather.
Many years ago, some automotive anti-freeze was alcohol based.
Very few people liked it, but it wasn't poisonous.

Ok so RV Antifreeze contains some ethyl alcohol ,but,what is the percentage?
Some RV antifreeze products are 20% ethanol, some are 10% ethanol mixed with propylene glycol, some are only propylene glycol. All of these are mixed with a majority of water.
Ethanol is there for only one reason, because it is cheaper than propylene glycol. I always seek out and enjoy paying more for all propylene glycol antifreeze. It is alleged that the presence of ethanol increases the stubbornness of the aftertaste problem and is harmful to plastic/rubber components.

I just bought a 2 gallon jug of RV anti-freeze at Walmart for under $4.00.
Man, that must be some kind of nasty vodka to be less expensive than that....
I have never seen a 2 gallon jug of RV anti-freeze in WalMart or anywhere else is this a new thing? $4 for two gallons is a steal.
I did buy -100 boiler anti-freeze at store close out for $2 a jug. Mixed it half and half with water and had enough to last quite a few years.
