Both of my DEF-burdened diesels (both Fords FWIW) routinely sit for days on end in Los Anchorage in the winter and fairly frequently take multi-day trips to Squarebanks and environs wherein overnight temps get to the -40 F or colder range.....whether its multiple days of circa 10 degrees (Los Anchorage) or a couple of days of -30-ish (Squarebanks), that's enough cold for the vehicle to lose any semblance of warmth.
...and I've never had a problem with DEF due to freezing / expansion. Also FWIW, my F550 plow truck regularly sits from end of May to early November: When I remember, I put a tender on it (I have a Schumacher model) but have never had an issue either way regarding battery charge.
...course, since it makes no sense to have an asset like that sitting for 1/3 of the year, I recently sold it....
