MILEAGE EXPECTATION
I have a 1999 International with a N-14 Cummins, 3.9 gears with a 10 speed. What should my expected mileage be with this truck pulling a hopper bottom. It has 430hp with a mid rise sleeper.
Also, what advice to improve mileage. I am currently getting 4.3 pulling a ribbed cornhusker with no APU but engine needs major overhaul.
