All are long bed quad cabs. The 5.7 might be ok for mulling a relatively light trailer. It struggles to pull both of our trailers and cannot maintain speed in hills. Not to mention it gets about 8mpg doing so. Both diesels pull like Clydesdale horses and maintain at least 14mpg doing so. Empty they get about 23mpg on the highway, the hemi might get 14.When it comes to big trucks HP doesn't cut it. An extra 2-300 lb-ft of torque... Maybe wanna rethink your math?

What is wrong with his math?
Is that hand calculated because 23mpg from a 05 and 07 Cummins is FREAKING AMAZING, especially with this crap ultra low sulfur fuel we've been getting and all the additional emission BS and increased displacement on the 6.7L?
I have a 03 3500 Ram 6 speed manual (which has been said gets the best mpg of modern diesels) and have never seen over 20mpg on a whole tank (all highway). On the other hand my dad's 08 Hemi 1500 4x4 quad cab gets 17mpg and thats after climbing to 4000' elevation and he drives with the lightest foot known to man. He could probably squeeze 19mpg out of it all highway in the flats. I was averaging 20.5-21mpg on a trip back from TX but it dropped down to 18-19mpg once the speed limit went up to 75mph which had big rigs up my ass and passing me and hit a few grades.
