3.0 Duramax in Extreme Cold

[prfalcon]

I just ordered an AT4 with the 6.2. I have had that motor in my previous three trucks and really like it. However I have been going back and forth on 3.0 Diesel for mileage/range and the fact every truck reviewer and owner seems to love that engine. I only tow occasionally. It's not too late for me to switch the powertrain. I spend a lot of time near the Canadian border here in Minnesota and often see winter temps -20F and colder and am worried about fuel gelling and DEF freezing up. I am aware of the fuel additives and don't always have the opportunity to plug in. I have a good friend who constantly had issues with his RAM Cummins gelling up and has sworn off diesels for extreme cold conditions. I am sure GM sells a lot of these powertrains in Canada so maybe I am off base with these concerns. Thoughts? Experiences?

I only know of one person who's had the gelling issue, and it was last year in Enid, OK during a record-setting arctic front that got one of our company trucks stranded at the hotel with a useless 6.7 Powerstroke. My Cummins was parked outside at the same time in the same area and didn't gel thanks to the additives. I'd rather have a diesel for just about any severe conditions. That said my daily driver now is a 6.2 gasser.

Thanks for your reply. I think I am going to stick with the gasser.
