Ok, all you diesel truck owners. How does the new gen of diesel trucks work in the cold? I know the old ones were a bear. Never started, ran like garbage, no heat. Are the new ones any better? Still have to plug them in at night? Also if I go to work, and say it is right around 0 deg, is it going to start when I go home after 9 hours? If I do get a truck, it will have to be my dayly driver all year, so I need something that will run.
