Took my truck on its first road trip with me behind the wheel. My wife has drove it to Michigan and back twice while I was deployed but she never pays attention to MPG since she has more of a lead foot than I because she just wants to get to her destination as quickly as possible. The trip was around 350ish miles each way so we could to drop our daughters off at their grandparents for the next month while my wife and I get things in order to move to our next duty station at the end of the year. On the way there the truck averaged 19.9 MPG due to hitting a lot of traffic and having my 2 daughters which meant more frequent stops. However, on the way back with just my wife and I, we hit a sweet spot and was able to cruise most of the way without hitting traffic and averaged 22.1 MPG which I was amazed at! Both were hand calculated and actually my fuel economy displayed on the EVIC in the truck was only off by .2 both times. Truck is a 2018 5.7L QC 4x4 with 3.21's.
