Possibly: 15 city/towing and 20 mpg highway. This would depend on engine/IP condition and fuel quality. What gear ratio do you have, get the # off the door post tag under axle.

15 mpg city/towing & 20 mpg on a highway, sounds pretty good...

Are you talking about imperial or US gallons?

Depending on Axle ratio and transmission type.. with a 6000# trailer I dont know my f250 with 6000# enclosed trailer gets about 12 mpg. very much dependent on wind and speed..

Your milage will depend on type of tranny, and axle ratio. With a ZF5 manual tranny 3:55 rear end you could possibly reach 15/20 mpg but that would be about the best I would expect.

The actual for a dually would probably be a somewhat less, especially if you drive in a mountainous area like BC.

On the flats 15/20 sounds doable with a standard tranny and 3:55 rear end.

If you got an automatic, knock off 1 to 2 mpg.

Also if the rear end is 4:10 then take a little more off for mileage.

Diesel MPG is very dependant on terrain, elevation, load and the biggy is driving style.

Two identically equipped trucks in the same area with two different drivers, one drives a little slower, takes off a little slower and lets off the throttle a lot earlier when coming to a stop, against a driver that is either wide open or on the brakes hard can easily have a 50% difference in MPG.

Truck equipment is only a small part of the MPG equation.

I driven all sorts of terrian.....diesel engines are [were?] the engine of choice, being high tourqe, with good fuel economy...ask an independent truck driver of what he thinks the current prices at the pumps!

Getting good MPG's [IDI] is no different than any other engine...let it breathe...air intake mods & free flowing exhaust!

The biggest increase in Fuel economy is in your right foot....keeping RPM's under 2300 will give the best Fuel economy!

In my experience the F350's tend to be equipped more likely with the 4:10 rather than 3:55 gears. That will hurt fuel economy a bit. Better for towing and hauling so.
