I have had a new Ford and have a new Dodge and they both get about 8/10 pulling a 32ft gooseneck with one tractor with cab.Without trailer driving normal 15MPG is tops.Many people claim more but that's what I get.They both have plenty of power just too many pollution devices to steal mileage.I have had older Powerstroke and Cummins that got about 25% better mileage but not as much power.We don't chip or change them as it is costly and can void warranty.

Your figures make sense, a lot of people claim they get pulling what you get normal driving. Just wondering what one you like more the, does the inline 6 seem to pull as good as the v8.

my 97 12 valve cummins has gotten close to 26mph with a very light foot on the highway.
I beefed up the tranny and tuned the pump. Keeps up with new rigs now.

I personally have a 2007 Dodge with the 6.7 Cummins. I have all the emissions stuff removed. When driven like a car it will run around 18-20 mpg locally. I have gotten 22-24 mpg on long trips. When pulling a load, which it does often, it will range anywhere from 10-16 mpg depending on the load. The truck has 326,000 miles on it. Engine and trans are original. T-case was replaced at 320,000 miles due to operator error.

I service several 6.6 gm's in my shop. Many are in the '05-'10 range. Several have 100,000+ miles with one in particular, an '07 that has 230,000 on it. He uses it hard. Drive train is original. He runs 16-18 mpg empty and 10-14 mpg loaded. The others are all in that range too.

Really no difference also had a DuraMax which I also liked and it got 8/10MPG.One thing about the Dodge is there is more room under the hood and the ride is excellent.All diesel trucks had poor automatics but that has been changed and they all work as good as the Allison.I had to buy manual trans until they fiqured it out but they did.

Best not bestest, rather than that you said everything right. Or you could just buy a dodge.

You've converted me. I'm so convinced I went and bought a powerwagon today. Then I bought a chip for it that gave me an extra 250hp and 300 lb ft of torque. It's so amazing. I out pulled every diesel pickup on the road. I was towing 30,000lbs and I beat a 600hp semi pulling 25,000lbs up an 8% grade. When empty I get 19 mpg, and 11 mpg towing through the mountains.
