I have lived in Alaska for now going on 42 years....
As far as any type of antifreeze is concerned - I would tend to use my antifreeze tester to see what the TRUE concentration reading shows - mixing 65% Prestone antifreeze with 35% distilled water will actually show a different reading then using the same mixture 2/3rds antifreeze-1/3rd water with the Peak brand....just by looking at RV antifreeze itself with a label rated past -50 below F I laugh and say no -way ! as I lived in the arctic for too long - and I am a native southern Californian !
I never used any kind of RV antifreeze for my cabover for outside winter storage, as I simplify any RV life I ever get (only up to one month a year as I still am a working stiff) so I just never use the sink or toilet to begin with - as I purchased a portable toilet for the girls, and use my own honey bucket with a lid and a removable toilet seat to boot along with using a couple of Prestone jugs for #1 nature calls if I am not in the wilderness or a nearby rest stop or bathroom facility.
