My 2013 Duramax was used as a daily driver from our home in North Augusta, SC, to downtown Augusta, GA, (8 miles and a little over 15 minutes) for three years before I retired and hit the road. I idled it for a few minutes in the winter before pulling out of the driveway on cold mornings. Once a month or so, we took it out on the highway and it was used for road trips and to pull our travel trailer. We never had a problem with it. Once we hit the road full-time, it pulled the fifth wheel our first 11,400 miles. Great truck!
