My 2006 ram 3500 single wheel 4x4 long bed gets around 20 MPG out on the road empty, it will get 14 MPG pulling my 24 ft. Pace Shadow weighing 8600 lbs on the axles, it will avaerge bewteen 14 and 16 MPG empty in town with some short highway driving. I own a 36 Ft fifth wheel travel trailer with three slide outs, it weighs 11,800 on the two trailer axles and puts around 1500 lbs more on the truck, some on the front axle but most of it on the rear axle. The truck rides and feels better pulling the fifth wheel than it does pulling the car trailer The best mileage I got towing the fifth wheel from central Oregon to central Arkansas three years ago was right at 12 MPG, the worst mileage was from the eastern border of Okolhoma(SP?) on I 40 to the middle of the Texas panhandle into a direct head wind, it got a little above 8 MPG on that run at 65 to 70 MPH I had a 1998 1/2 24 valve automatic short wheel base 3/4 ton extended cab two wheel drive, it got excellent mileage until Mopar did a "emissions " recall to reflash the computer, it sucked after that I ended up having a freind, who worked at Cummins Pacific, install a industrial 230 HP program into my onboard computer, that made it better but not as good as it was originally BTW, I owned three different car hauling trucks before switching to the CTD, 1973 1 ton crew cab Ford 390 with a C6 and 4.10 gears , 1957 1 ton Dodge with a 318 and a four speed, 4.10 gears and the first one was a 1955 Dodge 1 1/2 ton with a four speed and a two speed rear end with 9.50x20 inch tires, it orignally had a 254 C.I. Dodge 6 cylinder flathead truck motor in it and later I put a 1957 392 New Yorher passenger car hemi motor in it. None of the gas trucks ever got more than 10 MPG going to and from the races, never

Ive had a 1998 12v, 5 speed. Hauled a$$. Only got 15 empty, but boy would it push you back in the seat when grabbing gears. Then a 2000 auto v10, emty 11, with 7 k I got 9 with no power. Now have a 99 with 250k, 5 speed. Doesnt have the power the 12v had, but gets average of 19 empty and 14 with 7k. This is with 354 gears and 35 bfg tire.

Thinking about trading my 2011 Hemi 2500 for a Cummings. I love my truck but was thinking about swapping it while it still worth something. I average about 12 around town and 8 pulling 9000lbs. My current ride has 4.10's and does the job around my part of the country just fine but just want to hear numbers from the real world guys on the Cummings. I am also considering the 6.4 Hemi. I figure the mileage should be on a par or a little worse the 5.7 but with more grunt. Comments, Thanks Jim T.
If it were me I would look for a low mileage 5.9 truck. The new trucks get less mileage and they have a lot more emission stuff on them to give you problems. With a tunner you can make just as much power with the 5.9. I like that I can run other than ULS desiel in my truck. A couple of years ago the power went out in our area. I was very low on fuel. Luckly I had some off road desiel in the shed or heating oil? Put 5 gallon in and was able to drive 15 miles to the next town where they had power to fill up my truck and get supplies. It is something to consider.

I would only buy an 06 and older 5.9 and only a manual trans if I was to buy another diesel truck.

I agree. My 12 valve 5 speed gets super mileage, and my buddy has an 06 Mega Cab 6 speed 4x4 and it gets great mileage too. Cheapest thing I own to drive.

I don't drive my 04 QC 2wd 305/555 long bed much, so rarely check mileage. But last week I did a 700 mile round trip to Oregon, twice. Both times I got near identical mileage, 19.5 empty, and 16.4 flat towing a 3800 vehicle. This was going over some pretty steep mountain passes, and cruise control not working. I was by no means babying it, although I-5 in northern California is crawling with CHP's. So, with a speed limit of 55 towing, I rarely went much over 63 mph in that 50 mile section. The rest of the time I was mostly doing 65-70.

You guys with your stock cummins' are leaving A LOT of mpg and horsepower at the pump. I had a 95 2500 4x4. Twin turbos, 435 injectors, lazer cut delivery valves 4000 govenor kit and a lot of pump work plus a really good tranny. I averaged 23-24 on the freeway and 16 towing. That was at 600 RWHP. Now I have a 07 6.7 auto 2wd 3500. I have deleted the EGR and DPF all the way to the turbo. Added a free flowing 4" exhaust, AIRAID intake system and a H&S mini maxx programmer. It gets 24 on the freeway at 65 and 15 towing at 65. Its close to 500 RWHP. This is my old 95. click it.. VVV My 07

In all most every case with a cummins HP equals MPG. My 95 started at 18 mpg stock. My 07 was 16 mpg hwy. Now low 20s.

I've had thoughts of pumping mine up a bit with a Smarty, but dread the thought of possibly killing the 48RE automatic. Performance is all about how much you want to spend, and personally I don't need a whole lot more power than my stock 305/555 common rail puts out. I'm usually passing half the vehicles up steep grades with my camper on or pulling a trailer.
Then leave it be.... increased performance will increased the odds of failure in some manner be it trans, headgasket, or even a melted pistons. Granted you usually have to do some pretty stupid stuff to hurt em, but I've seen plenty! I was pretty disappointed with my 01 4x4 when I got it, but I built a good trans with an awesome torque converter, some RV275 Bosch injectors, and an Edge EZ. Simple low end mods which totally turned the truck around for my towing needs. Personally I question alot of the MPG number stated here, but I also live in a pretty god awfull area with steep long mountain passes. IF...I drive nice I'll see 16 in town. On the highway...17-19 in the 75-85 range. Towing...best ever was 13, usually 10-12 and this is a 24ft enclosed trailer 8K total. One time I was bored and drove across the desert to Palmdale to drop off my race trans and kept the boost low, and the average mpg on the overhead as high as I could. I don't think I went over 60mph the whole day and on some of the steeper grades I was out of OD to keep the numbers "up". I got 23mpg that day.

My 01 is a quad cab, shortbed with 5 speed... I get right around 19mpg and that's all local short trips and I like to get moving fast, not easy on the pedal When stock I got about 17.5, since added 100hp injectors, edge comp(stays on level 5), 4" exhaust and cai. I also run heavy 33" mud style tires. When towing a lot, which the usual haul is up a long steep hill that's a few miles long to take in scrap car, I avg about 17.5 those weeks. Conservatively my truck is 350/850 to the wheels, sure makes a fun driving truck too

'01 24v Cummins, auto, 3.54 gear, 35" tall tires, 4x4, quad cab short bed. 4" straight pipe exhaust, BHAF, and a small 60 hp Superchips programmer.
Mine gets around 20-21 mpg combined city/highway (mostly highway). Don't do much city driving w/ it and I've honestly never even bothered to check the mileage when towing. I check it by hand, although the dash/overhead readout is always real close as far as the average mpg.
