15-16.5 mpg city, when i drive really easy.
10.5-11.5 mpg highway towing 10,000lb Airstream.
Don’t drive enough highway without the trailer to calc mileage.

This is more what I was expecting. Are you running the original injectors? Nice airstream btw
Thanks!
Original injectors as far as I know.
I bought her used in 2015.
The other thing I noticed was a full 1mpg drop when the weather gets cold.
I figured it’s a combo of winter fuel blend and a lot of idling “warming up”
My 2000 7.3 had almost the same mileage when I bought it.
Prior to rebuilding the injectors I took some steps to that increased mpg.
Changed the oil and filter using Shell Rotella T6 Synthetic.
Next changed the fuel filter and did a Sea Foam Flush of the injectors.
These things did help increase the fuel economy by about 2 mpg.

Updated mileage= This time it was 250miles worth and 13.3mpg. It appears to be consistent at least, just not good. I haven't tried the seafoam yet. That is next on my list.
When you order your new fuel filter be sure to check you current fuel filter cap. The one on my truck was one of those cap/filter combinations that the PO had put on there. I had to order a regular cap for it so I could use the replaceable cartridges.
So it's been awhile since I updated. My last fill-up was 338.1mi at 13.6mpg. That was with 3 cans (16oz) of seafoam in the tank. Next up is to try the fuel filter replace and fill with seafoam.
The tires are 245s, so basically stock. I did the fuel mileage by calculating miles/gallons. First time was at 105 miles, second was 204.3 miles and topped off at each fill-up.
You say the tires are "basically stock". If you convert the metric sizes to standard and then take (new tire diameter / old tire diameter) and multiply by your miles on the odometer/trip, that will be the actual miles.
It doesn't sound like they are much different, but this could "add 1 mpg" or so to your results just because you now have an accurate measurement.
It's amazing how much difference even a small change in tire size makes. The easiest way to check your odometer accuracy is to compare your indicated miles against the highway "mile markers". In Ca at least they are the white posts placed every half to one mile intervals. They are accurate to within a matter of an inch or two, depending on where they wind up on the road.
