How will my new F350 behave in cold temps?

I can remember using a stove pipe w/ 90 deg end, propane weed burner and a piece of canvas to cover the entire engine to preheat here in Alaska on large trucks. And when we flew out to the bush we would drain the oil and pull the battery and reinstall to fly home. Some of the old Cummins engines had a compression release in cab, give a shot of starting fluid, run around pull compression release get engine turning over, release lever and away you Go. On our Ford pickups we drive out to our cabin, sometime staying for a week in -20 deg and have no problem starting with senthetic blend oil and good battery's. No electricity to plug in!
