Even in a place with no hills and at sea level, your not reliably getting 22 mpg. Short of being pulled by a tow truck, that aint happening.
2003 cummins vs 2022 gas. Obvioulsy the cummins has more data points but the 6.4 truck here seams typical and accurate

Comparing a modern vehicle to a 15 year old vehicle has little value.
A lot of innovation occurs in 15 years.
Any 2019 vehicle is superior to its 2004 version.
That's comparing apples to oranges. Those 2 trucks are not even remotely close.
Just say no to the payload police ">

It's quite common for owners of todays gas powered truck to compare the performance to yesteryears diesel. Nothing wrong with it as long as its' presented as such.

Has nothing to do with the 2 trucks being compared. Not part of the equation. Although 10ish mpg out of a 3rd Gen diesel (or most any diesel of the last 15+ years) towing a 10k 5ver is avg/reasonable and tells me you drive quite “conservatively.”
And based on that I could wrap my head around 10mpg towing the same trailer with a new 6.4 8speed gasser. As in, not “that” far off and maybe achievable driving for mpgs.
But 22mpg, bobtail, out of the same truck is a pipe dream.
Although I bet ole Back of the Pack/Slowmover could “almost” make that happen with his widely publicized hyper-miling techniques!
Reality is, the empty mpgs claimed are not an average or overall or repeatable except in maybe the most very controlled and advantageous situations. Would love to get on that bandwagon, but the 3 or 4 dozen gasser 1/2 and 3/4 tons I’ve had over the last 20 years And the million or so miles accumulated tell me otherwise.

Sorry, late to the subject.
We just traded a 2016 Ram 6.4 for a new Ram 6.4. The 16 Ram towed a fifth wheel to Alaska, around Western U.S. and to Florida and back to North Idaho, and it did just fine. We averaged 8.5 MPG hand calculated towing.
The new truck just finished a trip of 2900 miles through the Western U.S. and the Oregon coast---averaged 9.6 MPG hand calculated.
Our trailers weighed between 10,000 and 10,300 (Momma's shoes weighed a lot!!).
We were happy with the 16, but the 2023 Ram does a better job in our opinion.
See ya out there
