Thank you all for the feed back. I read some articles that it does not need plugged in unless its below zero due to it being a newer diesel. It will be outside parked and used here and there during the winter months. I typically use my beater on a daily basis to go back and forth to work.

Bought the new 2020 AT4 3.0 Duramax. This is my first diesel and was wondering if it needs plugged in during cold days!
