That is 'cool' 
.
-20F is about -29C, which is a regular winter for me here. Past few years, it hits -38C plus windchill several times a season. My truck sits while I'm at work but I plug it in on a timer about 99% of the time I know I'm going to use it.
Except last year. It was a 3 week cold spell, my truck wasn't used in five days at -35C but a cute little number a few doors down was struggling outside at 5am. I cringed, but I started up my 6.7 without being plugged in. It was a slow crank but it went first go. Ran it for 30 mins to get to operating temp just to spend a few minutes boosting a Yukon Denali. I ALWAYS get a smile and wave now though.

I knew that Ford had a test facility in Thompson, Manitoba! There is also a U.S. military base there too. I actually live 3 hours north east of Thompson. As for cold starts, I'm pretty sure I have everyone beat. I've started my truck in -48C (-54F), not including wind chill, without my truck being plugged in. It was supposed to be plugged in, but I either forgot or some how it got unplugged during the night. Either way, I hit the glow plugs three times in a row and it fired up like a champ! That is why I run full synthetic oil. I try not to use my truck once it gets passed -30C but I can't control the weather on days when I need to use my truck.

Since our trucks don't use evaporative cooling like our bodies do, wind chill will cool them faster, but will still not drop the temps below ambient. A -120° wind chill in a -50° ambient will still only drop your truck to -50°, but in a much faster time.
