John E Davies Posted May 31, 2017 Author Share Posted May 31, 2017 Just got home and after 3025 miles at highway speeds we got an overall average of 14.5 mpg. We saw a low of 12.4 while climbing into ferocious headwinds (40+ mph) and a high of 16.4 in milder conditions, descending. The Cummins 5.9 definitely noticed a trailer in back but it didn't slow us down on the grades. I maintained 65 mph mostly, with 70 mph when forced to by traffic doing 85+. It was very relaxed cruising - check out the tachometer: 1750 rpm at 65 mph. I love a big diesel for long range towing.
