Guess I got one of those non-magical trucks. Just my luck!

Thanks for the info, Deuce...


I made an hour each way trip (highway) recently and my mileage jumped up from 14 mpg to about 16 on the mileage meter in truck, so I figure once I'm on the road for my annual Kentucky road trip this year ( first road trip w my truck )...I'm shooting for over 16 with just straight highway driving and no city stop and go.

Anyone notice the phenomenon of towing mileage is in the 9-11 range regardless of trailer. I have 6 different trailers/items I tow. The biggest/heaviest is a 31í fiver with a jeep, boat or ATV trailer behind it. I also have a utility trailer that maxes out at 14k, a backhoe trailer with tractor. It doesnít matter which I tow, I get about 10 mpg. I recently had to tow the ATV trailer 300 miles. Half empty, half with a 500# ATV on it. I averaged 10 mpg. I have towed my fiver with jeep attached 1700 miles and averaged the same. I have discussed this with other local 6.7 owners, and they also see similar results. Our conclusion is the truck recognizes the trailer attached and the computer alters some parameter. Letís face it, the ATV trailer I tow with the ATV on it doesnít weigh 1000#ís and has very little wind resistance. Fiver with Jeep is in the 17,000# range with massive wind resistance and rolling resistance. There should be a big difference in mileage. BTW, 16-18 on the hwy is common.

I run the numbers and don't use the truck mpg.

For those that are DEF delete 18+mpg is probably realistic with not much of a load cruising at a reasonable speed. Throw in some extended hill climbs and 75 or so mph and / or a regen cycle or 2 then it may be a challenge.

In my experience, if you're traveling on a highway for a long cruise, towing mpg is all about the wind resistance. The weight means very little to these 400hp turbo diesels but the drag coefficient certainly does. I get the same mpg whether towing 6,000 lbs or 16,000. Trailer is shaped the same. Only exception would be an open flatbed or a bass boat.

I have to agree. My first trailer was a 8k TT and I got 10-11ish for the thousand or so miles I had that one. Upgraded to my current 14k 5th wheel and am getting 10-11ish. I tow only in Florida, so far, and its all pretty flatland. Once I get up to speed, 65mph, I see the boost stay around 5-6 lbs consistently. Same for both trailers.

That 20 mpg is instant mpg, not average. Now I know how some of these trucks are challenging the Prius's. I may have read it wrong but I know numerous 6.7 owners and none of them average that. If I reset on the highway at the correct time I to can match that.

That 18/19 mpg was highway driving with the DPF intact. I believe he told 21 or 22 mpg highway with delete. I'll talk to him again and find out. Talked to him the other day and his truck has 90k+ miles. He's talking selling it and getting a 2017...

I an not counting Idle Time. My unloaded MPG was at 20 or even 21 for several hundred miles down I 95. Never been able to do better than`19 before this trip. That's why I took the picture to prove it to my Ram Drivin Brother.
