OP stated "We went from Evanston Wy to Mesquite Nv". That is going from a mile and a half high to a quarter mile high. You could have just put transfer case in neutral, let her roll, and had trip average 20+ mpg.
Anyway, Ford truck, Cummins engine, great job, must have been a fun project!

You missed the 'and back' part, they had to gain all that altitude back.
While my post was TnC, didn't miss anything. If coasting, using NO FUEL to get there, and worst case coming home 12.7, still nets 20+ average.
