I'm on my third Cummins. First one was a 91 250 4x4 12 valve with 4 sp manual, 3:54 gear, locking front hubs . It got great millage going to and from work adveraging 21 MPH, 24 fully loaded with the flite way fiberglasscap and all our hunting grear and food for two weeks at deer camp had a 240,00 it when I sold it . Second one because I wanted a quad cab a 1998 2500 4x4 12valve with 5 sp manual 4:10 gear (
gone were the locking hubs because city people don't like to get out and lock them) It got a steady 18 MPH going back and forth to work and loaded with a Jason fiber glass cap and our hunting gear for 2 weeks at deer camp. It could only do about 83 MPH on the interstate with the pedal half way thru the floor. 4:10 isn't a gear for me I found out even though I pull a tri axel 22ft equipment trailer and a 22 ft' enclosed V nose trailer About 50% of the time.
Now the third I have a 2004.5 SRW 3500 4x4 6 sp manual 3:73 gear. Just got back from Wisconsin a week ago I got 22 MPG running a mix of 2 lane roads where you got to slow way down going thru some of those small one store villages and I 75.
This would be a truck that got close to 25 or better MPG if the Dodge enginners had any brains. I't got over twice the rated HP of my 91 but they will only put a 3:73 gear in it, again the city people got the locking hubs removed and no option to get them.
Would i buy a new Diesel tomorrow over a gasser. You bet I would even with the city-facation of them.
