Worst with present Dodge/Cummins was 9.9-10.2 mpgs (pencil figures) for 590 miles pulling my old very flat front profile square corners 11400 lb 5th wheel rv trailer.
We followed a large CO/TX/OK/KS thunder storm with 38-42 mph blow back head winds for that trip that lasted over 13 hours/590 miles till we made it home.
Worst ever was 4 mpgs in the late '70s using 460/454 with 4.10-4.56 gears carbureted big blocks one ton drw trucks pulling heavy GN flatdeck trailers. Gas stations had gas wars back then with 18-20 cents a gallon gas.
