A dually with 4:10 gears and a heavy truck you will be lucky to get 15 mpg it will probably be 12-15 mpg if it was a 5spd you would get better mpg.

I agree, the autos really sapped the power out of the 12V engines. 5 speed all the way.

Well in my common rail with 4.10's I get 15 - 16 in 50/50 city/highway driving, and about 17 all highway at about 63 mph, (1900 RPM). The 12 valve is an older mechanical engine, and the older mechanical engines tend to get better mileage than the newer common rails, most of the time. Different gearing I know, but my 92 W250 4x4 Auto w/3/54's will go about 16 - 17 in mixed city/highway and about 20 all highway. These are all unloaded numbers, fyi. If your planning on using the 3500 as your new work truck then it'd be a great way to go.

I have 3.55's on a 2500 2wd regular cab, 5-spd (about as light as these truck get.) Depending upon use, ambient temperature, and load, I have ranged anywhere from 17 - 24 mpg, hand-calculated, over nine years of ownership.

Figuring a dually, 4wd, auto that will probably be loaded more than I do, likley 13 - 18 at best, the auto may sap some power but it's not all that bad mileage wise, I had a 2500 4wd auto first with 3.55 rear end and routinley saw 22 mpg on the highway. The 4.10 rear end will sap more mileage than the auto. However - the 47Re automatic isn't the best choice overall; it can be build to take the torque, but until it is, it's not a matter of "if" it will fail, rather "when."

You are only getting 17mpg on the hwy at that low of speed? Hell, I cant even imagine driving only 63 on the hwy and my 06' gets right around 20 on the limited trips we've made so far. Got 19mpg on a short 130 mile trip to the lake last night, hand calculated with only putting in about $20 in fuel tank was embarrasingly empty. Also, the other diesels come out alot on Fridays so that was alotta hard driving just f'in around with the powerstrokes that seem to multiply overnight around here

My brothers 12 valve 2500 4x4 auto the automatic really eats up the power any time I drive the truck I have to get used to the slow take offs. No point in even mashing your foot to the floor it is too rough on the transmission. I caculated his fuel mileage and at best he is getting is 14 mpg. Pretty poor considering the truck is lighter than my F-450 that sees 11 mpg regulary with the 6.0.

Any dually truck don't expect fuel mileage your after capacity.

Is your 06 a DRW 4x4 3500 w/4.10 gears? I could see a SRW 3.73 geared truck getting 19 - 20, if you keep it below 70. Above 70 you start to get past 2k rpm and it just eats to much fuel. If you do happen to have a DRW 4x4 3500 w/4.10 gears then I'd highly doubt your getting 19 - 20, maybe based on the overhead, but definitely not hand calculated.

I don't floor it stop light to stop light, and I drive pretty conservatively compared to other drivers, and 17.8 is the best I've done in that truck. Going past 63 mph starts to put you past 2k, and after that fuel mileage drops to about 15 - 16 on the highway. 63 really isn't that bad though, and with the better mileage than at say 70, it's not worth driving at a higher speed, and you won't get there much faster anyway. Plus, if I wanna go fast and get good mileage, then I just drive the 1st Gen, it gets 19 - 20 without even trying.
