I am the OP and I’m still struggling to understand how working in a tent at potentially freezing outside temps (see link above for minimums and average minimums) can be anywhere close to comfortable. You have to keep in mind that work doesn’t stop on those days (or nights). And I’m pretty sure it’s not just a 9-5 shift. Obviously the people found the need for radiators which can be very dangerous in that environment.
