You got me beat!
I had to search for my post from 5 years ago:
40 miles on familiar roads with empty trailer: 36.1 mpg.
35 miles on faster, unfamiliar roads with empty trailer: 33 mpg.
75 miles back with pool stairs: 27.8 mpg.
Overall trip: 30.9 mpg.
That was 2015. 2015 F-150 V-6 EPA highway: 26 mpg.
Yeah, the worst tank ever was a huge win.
