Pleasant surprise
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 ...

I felt the computer was more reliable than hand calculating with my 2011 Powerstroke.
Huh?!? How is that even possible?
The computer accurately measures the fuel used. When hand calculating there is room for error if the truck is filled differently from one fill to the next. (either different method of filling or on account of the truck sitting a little different, different nozzle). I drove the truck from Texas to Alberta Canada pulling a 20,000 lb trailer when the truck was new. I hand calculated at every fuel stop and found it to be remarkably accurate. Then out of the blue my hand calculation disagreed with the display. The display showed worse than the calculator. I thought it was odd that all of a sudden the truck was getting a little better fuel economy......then the next fill the hand calculation worked out to be worse than the display and I realized that I must have not quite got the truck full the one time.
