Check your coolant for temp rating. (freezing point).

I was trying not to have to resort to a winterfront or high idle. If I have to spend that kind of money I'll get a Webasto and just not run the motor. I haven't looked at the fuel consumption numbers but it has to still be less than idling it that high.

Coolant was reused & tested for freeze, SCA & Ph when we did the t-stat. It only has around 50k on it.

I was just throwing the problem out there in hopes that others have had similar issues and it was a known fix.
