alcohol free antifreeze/not available in my county

PaulKethley

The ethanol free antifreeze does not exist in my area.  Nucamp recommends a brand called Purf Century.  Do I absolutely need this ethanol free antifreeze for my 2021 tab 400 boondock for winterization?

Ethanol is poisonous if you get some in you.  You are pumping this stuff in your water lines…  Your call, but personally, I wouldn’t use the stuff in my water system.

Poisonous, technically, but...most of us drink low concentrations of ethanol recreationally. It's isopropyl (rubbing alcohol) and methanol (wood alcohol / bad distilling byproduct) one usually might encounter and want to avoid. 

@PaulKethley - the short answer here is 'no', you don't. The ethanol that's present in many brands of RV antifreeze will accelerate breakdown of rubber gaskets/seals, but it's not going to do so in a single season. I'd avoid if if possible, but if it's not an option, this is a 'something is better than nothing' situation. You might also look into the 'blowout' method (search here on the forums) as an alternative method for winterizing.
