There is roughly a 1500 lb difference trailer weight wise between a 6.4 Hemi with a 4.10 and a 6.7 CTD with 3.42's per the 2018 info that I have.
What is the difference if they are both geared the same?
I doubt that the gas motor even has 3.42s available.....
And I can assure you that the diesel with 4.10s will embarrass the gas motor.
3.42's are the only option available in the 2500 & 3500 SRW CTD.
3.73 & 4.10 in the 6.4 Hemi.
6.4 Hemi 3.73 = 12,920 lbs
6.4 Hemi 4.10 = 15,920 lbs
6.7 CTD 3.42 = 17,480 lbs
There's pros & cons for each engine and for each consumer. What works for one person's needs might not be the same as another blofgren wrote:

Sounds like they need to go back to the Cummins for the 650 and up.
Exactly. We just passed on ordering 3 new F750 dump trucks at my work in large part because of the Ford 6.7L being the only diesel engine available in them. We went with Freightliner M2's with the 6.7L Cummins. :)
Cummins welcomes you and your company to the CP4.2 world. Also your shop better switch over to 10W30 oil and not run the standard 15W40 that everybody and their brother runs.
Back in early March I was on a Ram/Jeep/Chrysler lot looking at a Wrangler and noticed that 50% of the RAM HD trucks were gas powered. If you only include SRW trucks they're were more Hemi's than Cummins powered trucks. I never in the history of looking at HD trucks have I seen so many gas engines in HD trucks. Later walked over to the Ford lot next door (same dealer) and they were all Power Strokes.- Cummins12V98Explorer III

Most or the new Ambulances and tow trucks are now Cummins powered. - ShinerBockExplorer

We all know diesels are better at heavy towing.
Problem is, 90% of HD pickups aren't towing when on the road. For some people, they don't feel it's cost effective to run / maintain / buy a diesel just for the 5 - 10% miles they do tow.
If your duty cycle warrants the expenses (not just initial purchase) then get a diesel. Or if you just want one, and have the cash, go for it. After all, no one needs a sportscar.
You are right about one thing here. Many don't "feel" that is cost effective but they don't actually know. I did the numbers myself calculating initial cost, finance charges, tax, registration, fuel cost, DEF, maintenance, trade in value at 100k and so on of my 2014 CTD versus a 6.4L Hemi of my year. I came out ahead with the diesel by about $700. This was just calculating unloaded mileage for each truck. This won't be the same for most because fuel cost and resale values differ from one region to the next.
However, I would wager that if everyone actually did the math, the total cost on the diesel for most (not all) would be within $2,000 +/- of the gas version at the end of the 5 year 100k mile warranty that currently comes with all of the diesels. Most gassers values start to tank after this. That is really not a lot of money over the 5 year period. I spent more upgrading my F150 to a 4wd with an Ecoboost engine over the base 2wd 3.7L back in 2012 and both of those things cost me more overtime because it got worse fuel mileage than the base 2wd 3.7L unlike my diesel that gets around 3 mpg better than the gas version(when it was stock). - RoyJExplorerWe all know diesels are better at heavy towing.

That’s great! You spent $10k on the diesel motor in the first place. Now you’re only $5,000 to $5,500 in the hole. :)
I’ve only logged about 2.75 million miles, mostly in Ford Powerstrokes, and with today’s prices and poor fuel economy, there is no way a diesel will pay for itself or return money to offset the costs over any gas counterpart unless you tow heavy daily.
For fun, i’m trying a 3.0L Stroke in an F150. I basically pulled a deal to get the truck where the Diesel engine was a pittance over the EcoBoost. At 25-28mpg, and diesel costing a solid 25 cents a gallon less than gas here, I’m not losing money, but I can’t say I’m laughing all the way to the bank... even at 40k+ miles a year (average, pre-Covid).
Last time I checked, no gas motor was rated to tow as much as a diesel..... And I am not talking about a few hundred pounds..... It ain't even close.

The getting more back at trade in time...duh. No brainer, you dropped 7-9K more for an engine, what do you expect? Diesels will be preferred but that in no way means that a good, clean gasser is gonna sit on a used car lot forever like a bastard stepchild.
Since I bought my truck 15 months ago, this is the first time that diesel prices have been the same/lower than gas. Typically it's been .25-.40 cents more so that eats up most of the potential savings of better diesel MPG.
Oil changes are 2x gas. Fuel/water filters need to be changed out at $100 a pop with me buying the parts off Amazon and doing the work myself. Have changed out 2 sets already with 35K on the vehicle. $300 at the dealership.
I have an `18 CTD CC 4x4. Bought in 5/2019 so at the time Ram was offering stupidly incredible rebates/dealer discounts to get prior year stuff off the lot. Didn't want a 4x4 and would have preferred gas, but I walked out with my current truck for less than what a comparable gas 1/2T would cost.
Would I do it again? At this point in my life with my current needs and without the significant dealer discounts...NO. A gasser would serve my needs just as well and you CAN buy an EPA approved in bed gasoline transfer tank, just as you can for a diesel so you won't be having to stop at every gas station along the way.
Do I love the truck and glad that I do have it....absolutely. - HuntindogExplorer

With a diesel exhaust brake they come down a hill better than any gasser will do in tow/haul and engine compression. Also to build a gas engine that approaches the reliability of a diesel is going to close that price difference somewhat. And the gasser is going require expensive smog control features. The advent of the V10's was for smaller displacement per cylinder to help control smog.
