Question fuel mileage ford vs dodge

I have some questions on fuel mileage on 05 6.0 psd vs. Cummins 24 valve common rail while pulling 10-15k lb. Please comment your thoughts. I'm gonna pull a 48 ft flatbed gooseneck. I'm a diehard ford man.....but my friend says cummins will get way better fuel mileage. i want your opinion!

Our 5.9 gets better mileage than my 7.3 and my old 6.0. Not saying that is always the case but that was my personal experience.

I am getting around 15MPG a comparable dodge gets about 17MPG. I don't know about 6.0 Ive heard anywhere from 9mpg (with a screwy computer) and up to 20mpg (with the same screwy computer) I have never owned one. I don't think it would be significantly better but thats just my 2 cents.

Cummins will generally get better mileage mainly because it builds all of its torque at such a low RPM so it doesn't have to rev as high. Tire size, gearing and other things will also change MPG's.

I owned a 01 vp44 pumped cummins with 4:10's got 14 all the time empty loaded flat hills didn't matter. MY 94 7.3 ford has 4:10's does the same both trucks manual trans 4x4 i got rid of the 01 for a 08 dodge 6.7 has 3:42 gears manual gets 23 empty does 12 loaded so depends mostly on gears i think.
