Hello, I am doing some inquiring and was hoping any owners would be able to tell me what they are getting for fuel mileage (diesel) with these rigs specifically looking at dually in the one ton. I currently own a 2008 Ford F450 and pull a 35 foot Open Range fifth wheel. My fuel mileage on this thing is 6-8 mpg when pulling and 10-11.5 empty. I know there are probably other variables but just something in general on highway and in town pulling and not pulling would be great. thanks.

RAM should be ten or over towing. Depending on the gears you choose, the bobtail mileage will be 17 or 18 with 4:100's and maybe higher with 3.73 or 3.42. My SRW 3500 gets 17-18 with mixed driving. And 10-12 towing 12.5K fiver, have not towed enough with the Big Horn 5th wheel to give a report, however it seems similar. Got 18 at 80MPH in Wyoming and 21 at 65MPH. Chris

We have a 2015 Ram dually long bed towing about 16K and consistently get 10-12 towing and can get as much as 22 in perfect conditions but more like 18-19 when not towing.

I have a 2014 GMC dually. I get 8.5 to 10.5 towing a 17K fiver. I get between 15 and 17 on the highway empty.

My 15 will average between 10 and 11 mpg towing our 15.5K fifth wheel. Empty I have gotten as high as 22 but usually 18 or 19.

My 2013 Ram gets 10-11 mpg towing our high profile 16k fifth wheel here in the mountains of BC and 17-18 mpg solo.

OP...your 08 truck has the 6.4 which injects fuel into the DPF, 08 -10 were the years for this engine and they had the worse fuel mileage. I had a 08 f350 with the 6.4 and the DPF fell off, my mileage improved greatly!

my 2011 f250 with 6.7 and 3:55 gears would get about 10mpg towing, her replacement 2016 f350 dually 6.7 with 4:30 gears gets 11mpg towing at 65mph.
the trailer is a 38' 16k lb 5th wheel.

2014 Silverado 2500: 14 to 16 mpg towing a car hauler trailer loaded to the max; 21 to 22 naked
2016 Ram 2500: hasn't towed anything significant yet, but naked gets about 20-24 naked

All have been SRW

Those are all respectable numbers.

Pulling with gasser 505cid and the horse trailer - 12mpg and 17 empty. Never got much better with the four diesels I had owned previously. Plus gas is much cheaper now than ten years ago.

Same here. I don't see the mileage people are getting either. My mileage is more in line with yours. I've never seen 20 mpg unless I was costing down hill. :-) I believe it is the high profile more than the weight that affects mileage when towing. I have a 2015 3500 dually with Aisin and 4:10 gears.

HAND calc! I AVERAGE 9 in GOOD conditions Westcoast no wind at 60mph. There is NO way I can get 19-20 mpg on the freeway at 60 and I have 4.10's and Aisin trans. If I were to fuel get on the freeway drive 60 for 300 miles no wind no stopping or slowing then stop and fuel then hand calc I would be VERY lucky to get 18mpg. Most likely 17. At 75mph towing no wind I can get 7mph.

I can get as high as 10.5 on flat land no wind but then the mountains will be 8 or so.

I tow a combined load of 33K. I honestly don't care what my mileage is.

I don't get the mileage SOME claim but I fuel the tank to the top at every stop and hand calc so I know most peoples claims are inflated. I take the good bad and ugly.

I did not buy my truck for the mileage, I bought it to do a specific job. That is to haul around dependably our 23K home and it does that task extremely well.

Winter fuel? When did you do this. Wind really effects mileage also. Chris

2 weeks ago, from Phoenix to Durango. Most of the way I seemed to have at least a quartering tailwind, which is why I was so surprised at my mileage. Driving 60-62 while towing. Fresh oil change, new TV tires at 70 psi, fresh alignment, FW tires at max, running Diesel Kleen. Only thing I can think of that I did not change was the fuel filter, but should not have needed to.
