If your talking about Dodge, I know more of them that are cold natured than I have ever seen Fords.
I just never plug it in, It always starts, just a little groggy in the morning.
Yea, I'm talking about the Ole Cummins

I have herd of people having issues with cold cranks, but out of the 4 I've had, I've never had a problem. I had a '95 model that I had the fuel turned up on, she would spit and sputter for about 5 seconds and blow a cloud of white somke, but that was due to the fuel dilevery. (being turned WAY up)
I guess I've just been lucky
