2016 RAM 2500 Power Wagon with 6.4L Hemi
2016 Classic ~9,000lbs

I get about 9 MPG at level 65 MPH. My only solace is that it's the cheap 87 octane!

Thing that effect fuel milage:
Speed. To double the speed you must square the horsepower requiring more fuel.
Weight. Changes rolling resistance.
Wind. Headwind or tailwind component. That takes care of the headwind/tailwind portion of the wind direction.
Tire pressure. Changes rolling resistance,i.e., drag (drag uses fuel the same as speed increases).
Wheel alignment. Effects rolling resistance (drag).
Brake usage. Braking equals drag. Grade braking downhill reduces free wheeling of the tranny.
Accelerator. Manual usage verses cruise control.
Idling engines. Use fuel.
Traffic. Uses fuel because of uneven accelerator use as well as excessive idling and brake use.
Windows. Open or closed, effects drag.
Air dams. Lowers wind resistance under the vehicle.
Skirts. Think tractor trailers. Lessens drag.
External protuberances (things we mount on the outside of our vehicles). Drag. How smooth is the surface?
Some of these are infinitesimal, but added up and the fuel mileage goes down.

25 ft Excella on Dakota quad cab with 4.7 and 355 rear end I get 11-12 on the level but head winds, rain and hills take that down to 10 or a bit less. Of interest I got the same mileage pulling an 8 foot U-haul. Shows what the AS body shape means in towing at high speed. Without the trailer I can get 17 -20 no problem

2016 RAM 2500 with Cummins engine. Did roughly the same 1000 mile trip twice: (1) towing 30 ft Classic, 14 mpg average. (2) Without the TT, 18 mpg average, both from truck's computer readings. At a steady 55 mph on flat terrain, I often see 15-16 mpg towing, and 20-21 not towing. I'm expecting a slight improvement after truck reaches 6000 total miles, when Cummins says engine will be fully broken in.

6000 miles through the southwest and across the rockies - 9.7 2011 F150 Eco with a 25 ft Eddie Bauer. Lots of wind and 70 MPH when speed limit allowed. I would even go a bit faster in places like New Mexico where I had 20 miles of visibility and no traffic.
I am fascinated by how much interest MGP draws. Is it an issue of economics and affordability or is there something else which draws such attention?

2015 Ram 1500 EcoDiesel 4x4 pulling 2008 19' Bambi. Worst 16 mog / best 19 mpg. Without I have seen 22 worst to 26 best acording to gastracker. I do a lot of highway toll road driving and with 85 mph speedlimits + fudge factor of 5 mph getting the non towing gas millage is awsome. Towing i try to keep it below 70 around 68 cruise. I make trips from central Texas to Port Aransas, or Big Bend. See flat to hilly roads

Angry What's your towing mpg?

When checking your mileage, do not go by the tv display calculator but do the math. The onboard "lie-ometer" is notoriously inaccurate in most cases. My 06 Ram 3500/4wd/Cummins/dually shows a consistent 16-17mpg towing an 07 Classic Limited, 29'. Doing the math shows in the 12-13 mpg with which I am happy, towing in the 60-65mph range. I note the same variations driving empty, from 20-22mpg by computer to 17-18 by the math.

I notice similar variations in our 2014 Subaru Outback, but variation is only about 10%.
