I didn't work yesterday so my Duramax was sitting since Sunday morning. I forgot to plug it in Sunday so I started it yesterday evening let it run long enough to warm up and plugged it in. I parked it close to the garage with the front pointing east so the wind stayed away from the front. I plugged it in again tonight after work. I usually don't bother plugging it in until it gets below zero.
