Well, we here in Minnesota just had one of our worst blizzards in recent history. My neighborhood got 20" of snow. Yesterday I used my bone-stock M1008 to pull over 30 people out that were stuck, including other 4x4 Full-size trucks that were stuck. I had to pull one truck for 3 blocks before he could get enough traction. It got below 0 degrees last night, was right around 1 degree this morning when I went to start up "the beast". I let the plugs glow a little longer than I usually do, almost started on the first try. Finally got her going on the third try, but I think it was my fault the second time, could have done it then. So.... I don't do anything special to mine and it seems to start just fine after sitting outside all night in negative temps. I do have newer GP's, batts, and a new starter though. I'm sure that all helps. I have not checked my coolant. Should probably do that soon.
