TFL Truck highway MPG test 2500 Cummins

Amazing.
I used to be able to get 24 at 55~60 mph unloaded but since they went to ULSD I lost 2~3 mpg. BTW, my LOM would claim 26 mpg. :R
Still I guess I can't complain. :)

24 is better than our car gets. It will be interesting when he does the towing MPG test.

24.7 mpg. Lie-o-meter was LOWER again than actual.
