Back in May I did a ~2800 mile round trip with my '19 F-250 (see sig line) between the Seattle area and Chandler, AZ to visit my youngest daughter. I was lightly loaded and at the time had a Peragon aluminum tonneau over the bed. Overall for the trip it came in at 15mpg with the best tank being 16.8 coming north on US-93 through eastern Nevada at ~70-75mph. Worst tank was 13.3 due to headwinds going through south central Idaho.
