I am a Dodge man and have a 2500 6.7 for my personal truck but I wouldn't be against a Ford. The Ford hasn't missed a beat in 20,000 miles and is drivin hard.

I am pleased with my 2009 6.4 Superduty.
On the highway with no trailer I can get 20-22 mpg.
Combination highway city I drop down to about 17 mpg.
Hook up my 30' fifth wheel and I drop down to 10-12.
I don't drive it hard so it won't suck the diesel. If I get a heavy foot, the fuel gauge lets me know it.

I will assume your mileage numbers are based on the Canadian gallon. either that or you are running tuner and DPF delete package???

That's nearly double the mileage I ever experienced with the DPF intact.

I drive a 2008 F-450 with the 6.4L diesel at work. It just turned 90,000mi.
Had it towed into the dealer today with the engine overheating, and water in the oil.
Back when it was running, it averaged 8.5~9.5 mpg overall. 10% city, 90% highway miles with the cruise set at the speed limit.
Keeping my fingers crossed that the water in the oil is nothing more than an oil cooler o-ring or similar. Hope the engine hasn't just blown up. Dealer won't get to it until mid week next week.

Yes sir, moved here about a year and half ago from Co. Springs. I feel pretty blessed to live in this state. Like I said, I have been very impressed with the F-450 and yours is a beaut.

My 08 4x4 F350 with 3:73 gets 12mpg without pulling and 7 - 8 pulling the 40' Weekend Warrior loaded. If I got more than 13mpg I would think the odometer is reading wrong. But if I had it to do over I would buy the same truck.

Exactly what I posted earlier in this thread!
You keep your fuel pedal foot disciplined, and drive those diesels at 55-60 mph, and you will get optimum fuel mileage.
As mentioned earlier, I'm constantly being passed on the left by folks pulling their TT/5ths at 70+ mph..
Then they complain that they can't get decent fuel mileage. That also goes for unladen or running without towing or carrying a load......They drive at speeds that negate the great fuel-sipping characteristics of the diesel engine and complain that they aren't getting the fuel mileage of other folks on the forum.
This world is only "fast paced" as as long as we make it that way.
You'd be amazed how less stressful the drive while towing or even unloaded is at lower speeds, while the rest of the world races by in the left lanes.
On most trips that folks make to go camping, the difference between 55 mph and 70 mph, and getting to one's destination at a certain time, is only a matter of a few minutes.
When I tow and know that I'm getting 14+ mph cause I'm staying around 55-60 mph., that actually reduces stress, and actually makes for a more relaxing/enjoyable trip.
Some of you folks need to try it......You will go through some initial "Withdrawal" from being so used to pushing folks out of the way so you can get to your destination ASAP, but gradually you'll start to enjoy the scenery, and not be so caught-up in "getting there".
