I live in Michigan and my 2000 f250 sits outside. I have a timer on the block heater so it comes on 2 hours before I start my truck. **block heaters draw a lot of electricity at least older ones do** I would turn the key toward till the wait to start light is out it would fire right up and have heat almost immediately.
Older powerstrokes 2009 and older with 7.3 6.0 and 6.4 are harder to start because they use oil to fire the injectors so not pluged in they can be cranky but they normally start.
The 6.4 does not have oil fired injectors. I have had no issues starting my 2008 at temps well under zero. And that is without plugging in the heaters.
