Default Power Wagon 6.4 Fuel Mileage VS 2500 6.4 4x4 Fuel Mileage

It seems that fuel mileage in a 4x4 2500 6.4 is better than the mileage in a Power Wagon 6.4 - by a large margin if some reports are to be believed.

Some owners even estimate that performance and mileage in a 2500 4x4 would be better with 4.10 or 4.30 gears vs 3.73's. The 6.4 PW has 4.10's.

Am I missing something with engine tuning, etc. between the two models? As far as I understand, a short box 2500 4x4 with 4.10 gears is essentially the same truck as the Power Wagon, minus the slight lift, suspension, winch, and tire size.

Am I believing too much internet manure or are there differences I'm unaware of that hurt or add to mileage efficiencies between the two models?

How large of a margin are you seeing? All things equal from a power train perspective, tires can really affect mpg. The larger tires on the Power Wagon could be the difference of 1-2 mpg I'd think.

I don't own either truck. I have a Ram 2500 4x4 diesel, 2002 vintage. I have been considering purchasing a new truck with a 6.4 instead of the diesel option.

I don't know anyone with either vehicle I previously described with a 6.4, so the "reliable" internet is my only source of info for mileage.

2015 PW, all stock. 15 mpg for mostly suburban driving, 16.5 on highway.

BTW that's with 87 Octane, have never tried 89.

I get 14 with a mix of town and highway driving. On a 200 mile trip recently that was 50% 55 MPH highway with some small towns and 50% freeway my EVIC reported 20 mpg. Hand calculated I got slightly over 17 MPG. I was pretty excited about the 20 MPG reading but it just wasn't accurate. I'm on stock tires 3.73 gears.

I can see the difference happening. I had a 13' Longhorn and got low 20's in mpg. I leveled front end and got high teens, then I went from stock road tires to AT and went to mid teens in mpg. As you said, PW has more aggressive tires, higher suspension, heavier front end with winch, and solid axles.

My new to me 15 PW gets about 9 around town and I can see 13-14 on hwy with a light foot. But in all reality, my right foot isn't that light! If I set cruise at 65-70, the evic will read 16-17 on level ground. By the time I use a whole tank, I'm back to 13-14 manually calculated. Looking forward to exhaust, tune and cai for improvements in mileage, but then the right foot will come into play again.
Oh well, I do love this truck!
