My disappointment with the 4.5 GEN RAM

Vapor567 said:
I have a 2019 Ram 2500 6.4. My small complaints are with the Big Horn I have no lumbar or seat height adjustment. Wish the rear middle seat was a full seat as well. Besides that, I absolutely love driving the truck. Smoothest transmission I've ever owned, quiet cab, great towing truck, averaging 16.5 mixed.

I must be doing something wrong. I'm seeing 12.5 from my 2020 6.4 2500.
 
I’m in the 13s, probably 70% highway with stock tires. Driving through town Stop and go seems to eat any gains I make on the highway pretty darn quick.
 
Overall average is in my Fuelly below, but high 16 on the highway running @ 70 and in in town with stop/go traffic and 15 mile commute is about 13
 
Um, my average dropped to 7.4 after my first tow, 6.5 for the trip. Gulp. However, my foot is usually in it and I'm freight train length.

I was all jacked about the 50 gal tank, now I figure my range will be about the same as my 04.5 for which I was getting 8.5.
 
My avg (not towing) with a mix of highway and city so far is 17.1. Obviously more city driving would bring that down.
 
I just took a trip from Western PA to North Central PA, mostly highway with some small backroads blended in. I averaged 13.4 no ECO mode, luggage in the bed. I feel as though with the hills it really affects this thing. It's all about the terrain. I bet if I did the same drive in Texas it would be more like 16-17 mpg, maybe more. On the way back i left the ECO mode on and gained maybe 1-1.5 mpg more, not much.

Is that including towing? I drive pretty easy, fastest on the highway is 75. I have factory size tires/wheels but Cooper A/T that weigh about 5 lbs more than the factory Firestones.

12.5 is no towing, but primarily in town driving. I see low 13's when I go to the Lake and back (Same road used to net me 23 MPG in my 2014 GMC 5.3).

That is pathetic MPG for a pickup. My BIL drove a triaxle dump truck with a 500 HP 60 Series Detroit that got better MPG grossing 74K+ lbs. And it was not a pre-emission engine.

It also had how many gears? Completely different scenarios bud, apples to oranges. Worst I’ve seen is 11.5 hauling 8k. 24’ Tilt deck trailer and my 4runner. Can maintain 85mph no problem and acceleration is plenty sufficient. I get 13.5-15mpg unloaded city driving. 17+ highway.

I used to dispatch 20 trucks and they mostly had 500-600HP diesel engines. Our loads were 13'6" high, 8'6" wide and close to 80k gross weight. These trucks averaged in the 5.5-7MPG range. It would seem that we should be seeing an easy 14MPG at max towing.... Also, these trucks have 18 wheels, 8 of which are driven wheels. Look at the size of the TWO axle differentials (there is also a third diff, similar to an old full-time 4wd). The tires were 285/75r24.5, 42" tall and about 125 lbs each. All this certainly points to lost potential in the smaller vehicles...
