The newer dodges are good to go starter wise down to -20F without plugging in. If it were only 20F I would be in a lot of trouble as I often park mine where there is no way to plug it in. In places where it does get that cold you'll more than likely find that all of the diesel fuel at the pump is winter blend which you'll need to keep the fuel from gelling. The high idle when the computer is programed to do it is normal. On my 2015 it even decides how fast I can take off with the somewhat annoying torque management.
-20... I'm cold just thinking about that, and I am camping just south of Tampa right now!
I'm sure the truck CAN start that cold, but that is a LOT of cold thick oil that has to get pushed around at those temps. Plugging in will get that oil a little bit thinner and easier to push around and warm up the whole truck faster. Not necessary, but certainly has its advantages!
