    I've talked to 4 of my buddies (not in the business) who own Dodge diesels and they all claim to get 18-25 MPG. They range from 2005 3500 to 2010 2500.
    I currently run Ford's and when they pull a 20' trailer with three Z-turns and other small equipment, I am getting an average of 7 MPG. My mechanics have looked at them and says eveyrthing is functioning and not sure why the mileage is bad. My drivers says they dont idle excessively. They got to 2-4 commecial sites a day.
    The fuel bill is killing me!!!! Please help!!!

    They must be kicking the piss out of them at all times.

    I dont think so. I drove one of the trucks a few weekends ago to help a friend move and do some other stuff. We started Friday morning and finished Sunday night. I kept track of the MPG and the I got 6.4 MPG...

    I get better then that with my big block gas engines pulling a loaded 18 foot trailer in a very hilly part of CT.

    Ok, i have a duramax diesel and pull a 18 foot enclosed with 2 z's and a walkbehind, and its nothing but stop and go in the city.. Last fillup i averaged 11.9 mpg. I can get 18 city drivin if i am dead empty and light footin it below 2000 rpm.. Im sure the dodges can get that mileage too empty, but no way pullin a trailer like mine. Remember diesels get alot better mpg, but also are alot more expensive up front and to maintain. Its kind of like a pay me now, or pay me later kind of thing. I personally love the diesels cause they will last forever if you take care of them and the resale value is awesome! Oh, not to mention they will pull anything.

    Is it a 6.4? I used to have one and it would get 10mpg empty or pulling 10,000 lbs. If I get another diesel it'll most likely be a dodge with a 5.9 or a highly moded 6.7.

    With a 1999 dodge 3500 5.9 cummins manual. I get around 14 to 16 towing in the city. Highway without a trailer 18 or 19. All stock but a EDGE controller that lowers the RPMS at highway speeds. Hopes this helps.

    My 06 Dodge Dually will get from 12-30. It will show 16-34 on the computer but its 4 gal less than that at the pump. It depends on now I drive it. It got 15.2 pulling a 38' fifth wheel camper in the Black Mountains. But you have to run 55 at 1450 rpm. Had a guy with me who has a new Ford the other day. And I showed him what it done by rpm's he couldnt believe it. I wish it had 3.55 gears its got 3.73. My brother-n-law has 3.55 and he gets 22 pulling his race car trailer. Good fuel also make a difference. Pulling the lawn trailer I have been averaging 17 every week so far.

    Have a '99 that can squeak out 16-17 around town pulling a 20ft enclosed with two ztr's, and an '03 that is 13-14 with the same trailer. Both auto but the torque converter locks up at 28-30 mph on the '99 which makes all the difference
