My RV antifreeze froze!
Just -27 C yesterday and I happened to notice the pink stuff in the toilet bowl was solid. Not like water ice; more like frozen slushy. The antifreeze in the jug marked good to -50C was the same. I did a foolish thing buying two large jugs at an estate sale. It must have been antifreeze recovered from the guy's big motorhome with some water mixed in. It looked like new but is now clearly inferior to unused stuff with the same rating, which had no sign of freezing. Many people have said the pink stuff goes slushy but doesn't expand enough to break anything, which let me sleep well.
We are having a Chinook today, with temperatures rebounding to 1 or 2 C above zero. I took advantage of that to heat up the MH and winterize again with a new jug. No damage apparent, though the toilet drain won't open.
