I pulled my Jayco about 150 miles or so on Sunday and back the 150 miles this afternoon. I don't know how accurate the onboard mileage computers are but mine said that I was getting a little over 12 mpg towing each way. It was reading 21 to 23 mpg empty. I just bought it recently and can't believe the mileage. The best I could get towing with the Cummins was 10.5 mpg towing and 19 mpg empty. This Powerstroke is sweet.
If they are like most ,then you are around 19-20 empty, and just over 10 towing hand calculated. Have two vehicles ,and both read 2-3 high .
I routinely get 19-21 hand calculated on my 2014 CTD ,and it usually reads 20-23 to get 19-21. But still your truck is doing very well. Two friends with the newer 6.7 ford one is the 2011, and the other is a 2015, and neither get the mileage my Ram does.
