So what's the difference with a F150 w/3.55's?
That's what ring gear they use to get the MPG stated on the sticker
The Screws both weigh about the same. I don't know where You come up with a F250 SCrew 5.4, 6.5' weighing 7200? Prolly figuring a V10/PSD? Every site I've seen says right around 6600-6800. Go check the SD forum below. Theres a couple of guys that have weighed their rigs.
2006 F-350 SC/SB 4x4 5.4, 1/2 tank of fuel and me........~6300
i weighed in at the local truck stop at 6600 lbs
'99 reg cab 5.4, two guys, 1/4 tank, fiberglass topper.
truck in my sig with a full tank 6460 gvw 8800

I'd almost bet that If Bsimmer weighed His truck with a tank of fuel. He'd be damn close to 6500 lbs.
I think Your having a hard time dealing with the FACT that the F150 is really HEAVY! Just about as heavy as a f250. Leading to the FACT that both trucks (similarly equipped) are about equal in efficiency. And reduced payload capacity

Ok, first off, you can't get an F-250 with 5.4 and 3.55's...not an option...maybe it used to be. Right now 3.73 is the highest gear (numerically lowest number) you can get with the 5.4.
Secondly, even if we assume that the two are pretty close in weight, there is no way the F-250 comes close in aerodynamics. The highway fuel mileage improvements of the '09 over the '04-'08 don't come from the 6-speed...the final overdrive in the new tranny is not almost identical to the one in the 4 speed. A lot of the noticed improvement comes from the aerodynamics of the new truck.

Whats the point in the extra leaf then? seems silly to fit it on the max trailer tow pack if it's not going to increase anything.

Helps with rear sqaut i fyou load er up.
I have 3.73s in my F150 so thats why wanted to compare apples to apples.
I pulled my weights off this site. Look up curb weight in specs. It says base curb weight of F250 Screw. I assumed base meant with base engine too? Maybe not. At the end of the day wether they're 400lbs or 1000lbs apart, the F250 5.4L does not acheive the same MPG as a F150 5.4L. And for 09 w/6 speed. not even close.

In Your way of thinking. Either the 250 is more aerodynamic than You think, or the 150 is less.

4R70W 4th gear ratio = .70:1
6R80 6th gear ratio = .69:1
The 6 speed has helped in city fuel economy, but you can't say it has contributed much to a difference on the highway. You clearly haven't read any of the articles that reference how the '09 now has the lowest drag coefficient in its class (.416...6% lower than an '08) due to extensive wind tunnel testing Ford did in its development. A quick look at the truck reveals this like the "spoiler" built into the tailgate, how the hood slopes to meet the windshield, how the back of the cab is sloped, etc.
Anyhow, if you don't think aerodynamics play a huge part in fuel economy, you are in denial.
My SD with the 6.0 consistently got 2mpg less than my F-150 under the same driving conditions, and I have a hard time believing that the same truck with the 5.4 would have done any better.
Sorry, I have gotten waaayyy

I know aero make a big difference in FE. But You'd think it would have done much better than the F250 does? Must be the weight holding it back?

However, if you do the math, it does only come out to about $250/year difference in fuel expenses (assuming 15,000 miles/year and $1.90/gallon). The weight certainly doesn't help FE.

In trying to find some answers about vehicle load rating I stumbled on info about commercial load ratings. I am not sure how this applies to our trucks but it was interesting non the less. It says that there is a tolerance allowance of 5% over the max weight for the vehicle.
Texas Department of Public Safety - Commercial Vehicle Enforcment Provisions Relating to Vehicle Size and Weight
I also sent an email to the US DOT about load ratings, so I will see what they say.

I checked out a FX4 SCrew w/20s and 5.5ft box and it was +1,400 lbs. Forget exact #. In any event the 6.5ft box must have a big impact as based on that one the 20's don't.
So I'm curious: Does Ford weigh each truck after its built, then take weight off gvwr and print the sticker w/payload right then and there... OR do they have about a billion pre-made stickers (think about how many combos availablewith all the arious options) and then go down some spreadsheet and figure out which sticker to apply?
And does GM and the rest have these stickers too? I've never looked...
