Our last truck was a 2009 Chevy Duramax/Alison 4x4 crew cab long bed dually. It's total daily commute was approximately 6 miles per day, with less than 15 minute of run time. I also thought about this may times wondering about what that was going to destroy over time. Well, 6 years later, 168,000 miles, 46 of the 48 continental U.S. States traveled, and that little 10-15 minute trip every freaking day it was home, we had absolutely ZERO problems!! We also had one winter with temperatures in the negative 20's for several weeks. We didn't even use the block heater either, it was too much trouble. Don't worry about it.
