F-250 Towing Mileage Reduced by 25%
I took my 2015 F-250 4x4 6.2L V8 and trailer out for the first time this year. Truck has 15,200 miles on it and it is due for an oil change and tire rotation (right at the 5,000 mile mark). No check...

I just got back from a 1st trip with my 2011 6.2 pulling a 7640# dry weight 5th wheel. I'm not really sure how much extra weight I loaded into it but the water tank was empty.
I-64 from Louisville, Ky. area to south I-75 (almost to Tn.) through some pretty decent but not huge hills running 65 to 66 mph. On the way down the meter showed 8.7 mpg and after I filled up it hand calculated 8.56 mpg. The gas was cheap so I probably shoved an extra 1/2 gallon in the tank so actual mileage may have been a bit better.
On the way back I decided to slow down some to about 63 mph and the meter was showing 9.9 mpg and hit 10 mpg in a few places. We stoped to eat and I decided to slow it down a bit more to about 61 mph and ran that speed all the way home until I got off of the interstate. Even though the hills were smaller after I dropped the speed the complete trip dropped to 9.7 mpg. It looks like 63 mpg may be my sweet spot but I'll experiment a bit more just to make sure. I haven't filled up yet to calculate the real world mileage on the return trip but I'm guessing the meter is not too far off.
