Dont buy diesels for low mileage or inner city life. Large amounts of fuel can take time to heat and is often difficult to do in cold weather. When the truck interior gets too cold too hot or the batteries start to drain past a certain level the truck starts back up.
In any case letting your diesel idle for anything more than a short duration is a bad idea because while the engine will use little fuel what fuel it does burn will not combust completely because the operating.
Now that you are clear on should you allow diesel engine to warm up before driving off you would not mess up. Diesel fuel has waxy substances in it. There is really no need to crank trucks in the winter if you have done the right things beforehand. Refiners have resolved this problem by making winter blends that work better in colder weather.
