It is producing a nice flow of considerably hot air in about 3-4 minutes. That includes a one minute startup cycle. With it oriented as I have it, it's quite comfortable very quickly even on a night like tonight below freezing.
I am not sure how long it would take to heat the whole truck.
I'm going to create a YouTube video soon timelapsing a stopwatch and a digital thermometer.
