04 CC auto 4x4 SW- - 70+ MPH pulling a 7k enclosed trailer & 4 kids, on freeway with a few steep hills- - 11.4 MPG.
Overall combined average on 4k miles is over 16MPG. Best so far 19.5 MPG highway (twice).
And yes it's *very* speed sensitive. I get better MPG on state highways where I'm running slower, like 60 MPH.
The '01 Supercrew 5.4 never got over 15 MPG and got 9 MPG pulling the same trailer on the same trip last year. I'm loving the 6.0!

2 responses in this 3 pager. Choctaw. I too would like to find some one who may have put in 3.55's (an old post with no replies. do the 3.55's fit from a E-350 van?) A tech on another site did not think it was a good idea even tho the van could tow my trailer and the 235-85-16's are an option. Utahtom when it's hot, the engine (either kind) makes less HP; BUT the vehicle slips thru the less dense air with less resistance and greater milage is attained. High humidity will screw this up. Sounds a little strange but I prove over and over on the Salt Flats every year. I make more HP in the morning but I slip thru the air better in the afternoon. More info; A waxed truck get better milage too. They polished the P-51's just for that reason.

We used to clean and wax rotor blades for the same reason.

Hank,
I went through the same decision making process on whether to buy a 250 CC or a dually CC. I went with the dually with the 4:10, and I am so happy I did. Not because of the gear, but because of the added stability the dual wheels makes. I have pulled the same 10k 28 ft race trailer with my truck and my dad's 03 250 CC 6.0. There is no comparison. Compared to my dually, my dad's truck gets blown all over the place when a semi goes by. On the same interstate trip, Richmond, Va. to Florida, I got 10.9 with dad's 250 and 10.5 with my dually. However, I made the trip empty each way with each trip. Got 19.5 with the 250 and 16.5 with the dually.

Other than a semi passing you, i.e. just running down the road did you fell a major difference between the dually and the single wheels. I know there is a big one for semis I am wondering about the rest of the time. Most have reported no difference unless you get on a rutted road. Then the dually really walks allot.

Its better all the time, just most noticeable when a semi passes. Even empty, the dually is more stable...doesn't feel as top heavy. I have never noticed it walking on a rutted road.

Getting in a truck with the 3.73 and then into one with the 4.10 and trying to compare the tach differences for the same indicated speed isn't too accurate, nor is the overhead "lie-o-meter"

Well we passed on the dually, and the 2wd f350. We got an fx4 lariat for $1000 than they were gonna sell me the 4x2 and the same price as the dually. Seems to be very stable due to weight, had no problem with semi's on the way to work. Still drivin easy for breakin purposes. will have 300+ on it tonight when I get home. It is a big truck, almost too wide for my shed and too long. Guess I will have to add another just for it!
SHowed it to a friend who is a dodge guy and he really liked it. Said it was quieter and nicer interior than his 03 2500. Plannin a trip up to the mountains this weekend, just gotta figure out a mount for the CB, someplace for the brake controller. Dont want to drill holes in the dash yet. Anyone got any ideas? thinking of a wood rack for over the hump in front of the jump seat.

I have a ham radio that has a detachable face plate. The bulk of the radio was mounted under the rear seat and I did drill a couple of holes in the dash to mount the face plate just to the right of the cubby hole or there abouts.
