New tow vehicle...6.4 hemi or Diesel?

-
Needless to say, if you tow, Diesel is it. Also, I paid 40k for that truck in 2012, and today the dealer offered 35k sight unseen. so resale is a big factor.
 
Personally I’m looking towards the 6.4.... our pickup only leaves the yard when we go racing, or to the lake with the boat. More than likely we’ll just keep the ole 01 CTD around until I’m done with the racing hobby. We’re 18600lb combined (pickup, 28ft trailer, 2700lb Duster, golf cart, gear).

used diesels are bringing STUPID money right now....

been working on the product since 93... not sure I’d go diesel anymore.

....and I have YET to find a tech that likes or would own an ECO (puke-o)diesel what a flipping abortion!
 
Here is my recommendations
Diesel only
5.9 will get the best mileage hands down
6.7 makes a lot more power.
If you go the 5.9 route. DO NOT BUY A 2003 1/2 TO 2007!!!!!!!!!!
And here is my statement! I REPLACED MORE ENGINES IN THAT YEAR TIME FRAME THEN I DID ALL THE DIESELS BEFORE AND AFTER THAT TIME COMBINED.
Not saying you can't get 250,000 out of them years, but you better not chip it, And you had better have bought it new, and your maintenance must be superior.:soapbox: Rant OFF
With all that said i would still buy a 2004-07 Dodge before any year Ford of Chiv Diesel.(But i may be a little prejudiced:p)
I don’t know about that my 07 5.9 had 285 k on it when I sold it to a farmer in Mi. 2 yrs ago. Still going strong. But I did have to put a water pump on it at 248k.
 
I have a 6.4 in a 3500 ram, it pulls everything fine, but it is a thirsty pig, 10 mpg empty or loaded.
It sucks so much fuel it is only used for towing, no daily driving this truck.
Ive got a 13,000 lbs,box truck that does better than that, and its got the worst diesel ever, the 6 liter ford.
 
6.4 hemi is a 4.10 gear, no thanks with the 8mpg towing maybe 15 on the freeway
I have an 06 2500 5.9 Cummins it gets 16mpg loaded & 20 mpg at 70 mph.
 
Agreed
But the eng brake was only a dealer install, and only on standard transmissions. come standard on all 6.7

not true, the 2012 Ram Cummins comes standard with the engine brake, both on Automatic and Manual transmission, Installed by Chrysler as standard equipment on all Cummins equipped Trucks 2012.
 
there is nothing worse than listening to a gas truck screaming down hill trying to slow down from 10,000 feet to ground level, VS Running 1800-2400 under control at a leisurely pace
with the other diesel trucks out there is reassuring. I towed with gas trucks for years until I could afford a real Hauling vehicle.
I never got less than 11 MPG pulling 20,000 lbs, and averaged 14-16 pulling 12,000. No gas truck can come close.

2012 is a 6.7 2008 on, are 6.7's
 
Diesel, all the way. I've had both gas powered trucks and diesel trucks, and there is no comparison when towing....diesel wins hands down (especially for that weight).
 
I have a 2017 Ram Crew Cab with the 6.4, 4.10 gears, 6 speed auto trans. It was a big improvement over my 2007 5.7 hemi. I tow 35 miles to the track, and have 3 "hills" on my route. My trailer is 24' and only about 7,000lbs loaded. The truck does see about 4,000 rpm towing up the hills going 60-65 mph, but it has enough power to keep pulling if you want to go faster. I avg 9-10 mpg towing and 13-14 mpg with no trailer. The new 8 speed should be a tad better I would think, but don't have any experience with them. Wife and I bought a 2020 Ford V10 24' Class C motorhome this year to use. Just filled it up this weekend and we are avg 6.5 mpg for that towing the same trailer.
 
We have both at work. I bought the 2014 3500 with the 6.4 because the def was a new thing and didn't want to run into issues like the 08 Ford we have. We tow several large generators ranging from 10k-13k. The 6.4 is a little slow off the line with the 13k but has towed it fine. Just this year I bought new 5500 with the Cummins. It tows the 13K trailer like it is not there. Both trucks were ordered with maximum towing in mind. The fuel mileage is negligible between the two but I believe that is due to the difference in the added weight of custom bed and gearing between the two.
 
2012 is a 6.7 2008 on, are 6.7's
very true, I began towing with A 2500 with a 5.9 Cummins since 1996 thru 2002, and the 5.9 3500 from 2003 thru 2006, then the 6.7 from 2007 to the present 2012, and I still own that one. The 96 I had ran a Jacobs brake Installed by the Cummins Dealer in Phoenix, and it was a Godsend on that truck if you were heading in any Direction out of Phoenix.

In my opinion the diesel upcharge is worth every penny, even if you have to buy Diff.
on top of the performance and the beefier frame, suspension,etc the diesel money comes back in the end, and resale on a Cummins is outstanding. The 100,000 mile engine warranty helps too.
 
If it was me, the gasser, especially if you aren't towing that trailer other than just to race X number of times a year.
The gasser is cheaper to fix if it breaks, and for the money you save by not buying the diesel, it would take years to pay for the difference in fuel.
A 2020 6.4 mega cab 4 by 4 even with 3.73 gears is rated right at 14,000 pounds towing capacity
 
Let me throw another monkey wrench into the equation: I think if I'm going to spend this kind of money for the big diesel, I would like to have the load leveling system. Apparently it is not available on the 6.4 hemi models, only the diesel.

Yup I have the Ram air suspension on my 2020 2500. Love it. Also I would recommend the Ram boxes.

buddy has air suspension on his 2015 1/2 ton Ram.
Would be surprised if you cant get it on gas 2500’s.
That said, lots of problems with the air ride leaking, etc, etc.... seems to be worst in cold weather areas in winter
 
I have bags on my 02 Duramax, it helped out with the 12k lbs 5th wheel....Not really needed for my open trailer + race car.
 
I drove home yesterday from the track with my 06 Cummings with my enclosed trailer and all the other crap you need at the track, pulling a steep grade up to 7500 ft the speed limit was 50 i was going 55 to 60, could have prolly gone 75 if there was not so many corners. Diesel all the way.
 
I picked up a '90 one ton last August, Cummins with a 5 -speed.

LOVE IT.

But one way or the other, do not tow in overdrive unless you plan on replacing your transmission.

I drove it from PA to VA to get this '70, mileage on the way home loaded was 14.5

Most Cummins are 3:54 geared. I have a 95 3500 bought new, 230,000 mi all pulling pretty big gooseneck horse/stock trailers. A car trailer loaded is nothing for it. It has 4:10 gears and has never puled a trailer in anything BUT OD! Trans is perfect. But I agree with your statement. BUT IF I tried to run the roads in 3rd I would be going 50 tops!!!!! I get about 5 mi per gal less than what a 3:54 would get.
For a diesel to be worth the cost, you need to pull a load and put many miles on it. Mine is just broke in, but at its age , sooner or later the brake lines will rot off!!!!! or radiator rot out! or>>>>>>>
By the way, when the AT trans goes out, many times it is the brain box!!! not the trans.
Now, the old Getrag speed pulling in OD is a NO NO!!

Agree 100%
My 90 i had a GearVendor overdrive so i pulled in 4th(direct drive) and GV was the over. 5th became double over on the flat lands. without the GV, max speed was 65 mph, foot to the floor riding on the Governor for hours on end.

Depends on the year, from 06 up 2500s are 3.73 & a AAM 11.5 rear diff. Maybe Dana 80 in 1 ton still have 3.54 though
