RV antifreeze, although not recommend for consumption, is safe or it would not be allowed for potable water lines.
Only "problem" with the RV antifreeze is the flush and residual flavoring.
You do not state whether you are hooked up to city or RV park.
You also need to drain and protect the tanks. Even the Black tank can freeze and that leak will be really noticeable.
As you pump in the AF(antifreeze), the water in lines goes to the GRAY tank. This process also puts AF in the drain and PTraps!! This is "good"! Any water will possibly freeze.
Make sure the BLACK is drained and rinsed. Then run the toilet flush until AF is coming into the toilet. Pour some extra AF into toilet and flush to protect the BLACK tank.
If "hooked up" make sure all water is out of the Stinky Slinky. Raise the high end and walk all the way to drain end. It need not be dry but should have no low spots where water could expand and rupture the hose. Or, just disconnect, clean and rinse out and store.
Remember an ounce of prevention will sag you THOUSANDS of repair dollars.
Another "option" is to leave AS. Totally winterized and use the RV park facilities. You are paying for them...
Now, what about other items in the AS? Things in the fridge CAN freeze. Liquids like eyedrops, canned foods, etc, will freeze. Beer, wine, etc will freeze!!!!
So, will you be removing all these items as well?
We had a few "freeze" days here in Texas. I ran the built in heater without issue. But to leave it unattended and "away" would not be best. Is there someone you could get to "check" on its status while away and "prepare" prior to return?
