HI everyone, new to forum and just purchaced a 2004 dually, I pulled our 28 ft. camper (7800#) from Ohio to Pegion Forge and averaged 10.5 MPG @ 70 to 75 MPH
. 2 weeks later pulled my buddies 35 ft. (13000#) camper from Ohio to Charlotte N.C. and averaged 8.5 MPG @ 70 to 75 MPH
(55 MPH up 7 mile hill)
. It has 2500 miles. I have heard the fuel mileage and power will get better with miles, but how much better?

It seems to take time for the mpg average to increase. My 2003 pulling a 18ooolb gooseneck was getting 8mpg...now it gets upwards of 10 mpg...not bad for 24000 combined weight. My 1999 454(vortech or whatever) dually used to get 5 mpg pulling that much weight.


Now my 2003 has over 13000miles on it and the fuel mileage is still increasing slightly.


I am surprised at the mpg difference when empty vs loaded. Empty the 2003 can get as high as 16-17 mpg. Still better than the 1999's 10 mpg when empty.






ON edit: I think you will be glad you joined.....there is alot to be learned here, especially if your new to diesels.Edited by: Gradyghost

Thanks for the replies, I'm sure this as been brought up many times! I love my D/A and glad to hear it gets better.
I am a mechanic for a city here in Ohio, the only thing i get to work on is powerstrokes in transit buses and firetrucks, dumps, packers, etc.
