There's a BIG difference between the current generation Ram and the Dodge/Cummins trucks that you owned. You're comparing apples to oranges.tinner12002 wrote:

I tow 23k with my 15 RAM with 4.10's turning 1,750 RPM's @ 60. My combined weight is 33k. I get 9mpg hand calculated towing at 60 mph. This is West coast where I can be as low as 7 or high as 10.5.
I was wondering if you would chime in as I know you pull pretty heavy.
Not sure what the specifics, rpm and such were but when I towed my 16.5K toy hauler, my Ram was getting around 11mpg towing. To me 6.6 seems a little low but then I don't pull any faster than 65mph for an extended period of time.
Is that gas station to gas station hand calculated? Or rolling on the freeway and reset the DIC? I've towed between 8k and 10k bumper pulls with several diesels and only get above 10 mpg under 60 mph. Most of these were tuned and no regens. I track everything in an app so everything is hand calculated every fill up.Hannibal wrote:

And according to you sig line you have never owned a 4th gen RAM!
On the road towing with the lower RPM RAM may be quieter than the higher RPM Ford. ChrisCummins12V98 wrote:

To me 6.6 seems a little low but then I don't pull any faster than 65mph for an extended period of time.- I don't put a pile of miles on my truck but the difference in fuel economy between the Ram and the Ford still amounts to $1000 per year. If I was buying a new truck now I would mentally be adding 8k to the price of the Ford before making my decision on which truck to buy.....If this mileage difference proves to be a good indication of fuel economy over a wide range of driving and towing conditions I think it would be enough to sway me over to Ram.

Whats up with Ford? New everything and it comes in last. I wonder if they still have some bugs to workout to get better performance.
I've been wondering the same thing. With all of the hype for the redesigned 2017 Super Duty and increased ratings on the 6.7L diesel I fully expected it to blow the other two out of the water certainly on performance but also be more competitive on fuel economy.
In typical Ford fashion, they will work out the bugs by about "Job 3" on the redesign..... :B
In the meantime I'm still very happy with my decision in 2014 to leave Ford and go with the Ram/Cummins. Just serviced her today and she's ready for towing season. Now if only the weather would cooperate.... :(2001400ex wrote:
A few points of interest.
1) not many people pulling 22,800 drives at 70.
2) would be interesting to see the difference if a full faced fifth wheel were attached.
3) I know it would take a lot longer, but they should do it over 400 or 500 miles. Something more than just 98. And track regens, that's a huge deal. If the Ford went through a regen during the route, the mpgs would be off drastically.
4) at least it's realistic. I read and hear too many stories of "I get 12 mph towing 15k pounds at 70 mph." Yeah no.
I'm only hooked to 20-21,000 but I usually run right at 70. I let'er back downext a little on the hills going up but I will also let'er roll on the down hill side a little. My truck has 3.42:1 and I average 9 all day long. BTW last time I checked my 5th wheel has a full front on it. I'll never get 12 if I dropped the boat off but it would be real close at 60.ACZL wrote:
The Ford also ran at 2100 RPM's while the Ram was at 2000 and GM at 1700, so I could see why the Ford used more fuel. Odd that the Ford was at a higher rpm than the other 2. Wonder what gearing was in each?
Ford and Dodge were 4:10. Chevy was 3:73.
Being at higher RPMs doesn't mean burning more fuel in a diesel. When you downshift, notice how you have to back off the throttle a little? Or if you have a pyro, when you downshift up a hill, the EGTs go down? It's because you need less fuel at higher RPMs. I wonder on this test if they downshifted the Chevy to 5th gear what the effect would have been.
