Thanks guys for all the responses. I read about a one ton dually a few years back in diesel power magazine getting 32 mpg on the highway empty... I'd like to hit 30 mpg on the highway empty and it should be easier being I have a 3/4 ton single axle. I'm building a highway truck to go to California and back repeating... Should I consider selling this truck, and getting one with a 5 speed?
I remember that magazine article..... We've talked about it a few times on these forums too. Where they took a 2wd dually and basically made it completely impractical, while driving impractically, in attempt to get the most fuel mileage possible. It was a fun read but thats about it.....
The best fuel mileage anyone will get with these trucks is typically around 16-18 around town and 20-22 mpg on the freeway. Thats real world driving in traffic doing at least the speed limits. You can squeeze out maybe 1 or 2 more mpg if you try hard, but really the only way to get more out of them is to reconfigure programming and fool sensors into running false parameters. But good ol' fashion mild right footed driving is still necessary as well.....
I believe Moparman is the reigning champ for fuel mileage, so if you're truly interested in getting the most fuel mileage possible in real world situations, do what he says.
