Oh, and I believe Ford’s new PowerBoost is rated at 24MPG combined, but I think on those you can the get 3.55 gearing so that would make a difference also. Even the 3.73 would help I’d imagine.
Just an FYI the gear ratios that were posted in that chart are no longer accurate either.... We have minor gear ratio changes with the new 8HP75 transmission
4thGen / 5th Gen
8HP70 / 8HP75
First – 4.71/ 5.00
Second – 3.14/ 3.20
Third – 2.10/ 2.14
Fourth – 1.66/ 1.72
Fifth – 1.28/ 1.31
Sixth – 1.00/ 1.00
Seventh – 0.83/ 0.82
Eighth – 0.66/ 0.64
Reverse – 3.30/ 3.45
You will love your truck with the new diesel, my Rebel diesel is awesome, it only comes with the 3.92 and it is a good combination, it does rev more on highway speed, in my case here in Northern Ontario the speed limit is 90 kph or 55 mph and I usually go 100 kph or 60 mph @ 1750 rpm.I ordered my 10th edition limited long horn 3.92 gears eco diesel. My second one, love these engines! Won't be here till March 2021 I have. 2014 ecodiesel ram long horn with 3.55 and it fine too, get 22 mileage per gallon all around driving, before recall got 25 miles per. And tows good, but half the fuel milage, which is good for towing. My friend has a 2016 eco diesel with 3.92 and love it's. say it's worth the less fuel miliage. I hope this new motor wholes up like last one? My EGR is still good on 2014, but there is a recall on it. It has 140,000 miles on it.
Try slowing down a notch? I don't think the 3.21 would make a huge difrence at those speeds. I can get 28-30 at 72mph in my 3.92 Ecodiesel no problem. Don't forget your truck isn't broken in yet and with cold temperatures you'll get worse mileage.I so very much regret not reading this forum until after my purchase. Last week, I purchased a 2021 Laramie Longhorn with the 3.0 EcoDiesel and 3.92 gearing. My trade in was a 2019 Ford F150 with the 3.0 PowerStroke V6. In my side job, I normally transport 20 bumper pull travel trailers annually, weighing between 5000-9000 pounds. My biggest complaint is HIGHWAY MILEAGE! I drive normally 80 with the cruise on going to pick up these trailers empty and averaged 25-27mpg with my Ford. Driving home the best I can get with the Ram is 21-22mpg. This figure alone has already got me looking to see when I can get out of the truck without loosing way too much money. Yes, I am quietly kicking myself for not reading about the difference of the 3.21 vs 3.92.

agree with you on cruise its pretty aggressiveI think that there's a lot here that is left unsaid.
What trim was your F150? What gearing was it equipped with? Did it have a tonneau cover? Did it have running boards?
And for your Ram. First, you did buy almost the heaviest trim level.
It comes standard with running boards I believe. I'm pretty sure that the running boards I added to my truck hurt my mileage.
Does it have the ORG or another package that adds the AT tires?
Lastly, don't believe the EPA estimate on the sticker for these rams...they are only correct for a tradesman truck with the same cab, bed, gearing and engine. It's especially true when you're looking at a Longhorn or Limited which can be quite a bit heavier depending on options, the Rebel trim is another where there is a large discrepancy because of the factory lift and off-road tires.
Another comment, I find the cruise control on the Rams to be quite aggressive. I find that my truck may downshift to maintain speed up a small hill, whereas if I control it with my foot it would not change gears. You might get better mileage controlling speed with your foot.
Beyond all that, how do you like the interior of your Ram compared to the Ford you had?

WXman, you keep posting this same misinformation.
Pretty much equal is not =eads, and it's wrong in this thread. Read this chart, look at the numbers, and please stop posting bad data. You're confusing other people as well and possibly causing them to purchase the wrong gear (costing them mpg).
The shaded cells are where the 3.21 and 3.92 are pretty much equal, just offset by 1 gear. You can see the difference is minimal.
You only benefit from the 3.92 if you're pulling a very heavy load (to get off the line; while towing at city or highway speeds, both will have the same final ratio available, just offset by a gear). Or, if you plan on offroading like the rebel, where the 3.92's extra torque in first is a benefit for rock crawling.

Your table proves WX right. None of the ratios are equal. Nearly = is not =. Plus, at normal egal top speeds the 3.92 gearing is going to use that 8th gear much more, while the 3.21 will drop down to 7th unless going on flats with very lite touch.WXman, you keep posting this same misinformation.

I side with WX.
Your difference table proves his point. At no place are the

Exactly, people are always mentioning their tow rating which doesn’t matter. You’ll run out of payload before you can ever tow 10k lbsTow ratings are gimped, just like EPA mpg numbers are.
With our 8 speeds, in the real world, you won't see much difference towing between a 3.21 and a 3.92, sorry. Just the first and second gear. Take it a little bit slower off the line with the 3.21. These trucks are not that well equipped to handle over 8000 pounds; the suspension is squirrely, the payload is too little, and the truck is not heavy enough to control the tail.
Guess I’d just slow down a bit, but thats me. Still sounds like a nice truck you have.I so very much regret not reading this forum until after my purchase.

All very good points. I was too lazy to ask many of the same, especially trim level. A Ford XLT has nothing to compare with a Longhorn... just sayin’ as I had an XLT and they are/were p l a i n...I think that there's a lot here that is left unsaid.
