| fuel mileage
any reports on fuel economy for the 2500 or 3500 08's I was looking to buy one.... they sure do ride nice and have good acceleration compared to my 02 DMAX I am currently getting 11 loaded 18 empty, carrying one L shaped 118gal fuel tank and one 53gal square tool box and 5th wheel style goose neck hitch. my truck stays loaded most of the time; hauling fuel and what not. I pull around a 287B rubber track loader on my trailer.
thanks for reading.

| the newer Diesels(that includes the Cummins,Duramax and the PowerStroke)have the EPA stuff one them have been suffering with lower fuel economy so i would highly advise you tp try and find a 06 to 07 classic duramax without all the EPA crap on it..

I have an 07' LMM 4x4 CC Z-71 with 4,200 miles and I'm getting 19-20 mpg on the highway unloaded. I'm completely happy with the fuel economy compared to my old gasser, but I'm gonna put a few miles on it and try a programer to see if my mpg will increase a little. | |

We also get this millage when empty. The towing millage is what were particularly concerned with as this is really what costs when it drops below 12, and you seem to eternally looking for a gas station, with low sulfur diesel.
Also, be very careful with the chip. They can trash your transmission and void your warranty if you are not careful. Most dealers seem to be on the lookout for them and I have heard some ugly, expensive stories.
