Excursion v-10 4.10 gears
I recently bought a 2000 Excursion limited with the v10. The tag on the axle indicates it has a 4.10 rear end. I get approx 14 MPG with just people on the highway and approx 11 around town. My question is does anyone tow with this rig setup? I am going to be towing a 8000# TTrailer and would expect arounf 10 MPG. Any thoughts or experiences with the Excursion?

Why would there be a tag on the axle stamped 4.10 if they are not 4.10's?
No code on the door jamb, tried that already.
How do you use RPM to determine gear ratio? The only way I ever calculated gear ratio was to turn the tire and count driveshaft revolutions and that was never accurate enough?

You see, you just can't get 4.10s with the V10.
Go to the Super Duty FAQ to find out the RPM you should be turning while on OD for a given speed. The differences between 3.73s & the available 4.30s is quite large so there shouldn't be any mistake.

4.10 gear availability
I checked with a friend and he identified that Ford offered a 4.10 in 2001. He said my truck could be a late in the model year where they were able to get the 4.10's with it. I will check on the info you suggested.

New question is it 250 or 350 chassis
Monsta or whomever, I keep getting different thoughts on whether the 2000 Ex is based on the f250 or f350 super duty chassis. My truck friend says that only f350 and above have the solid front axle. He called it by name but I cannot remember it right now. If you look at the payload on the varios brochurs and web sites it seems like it is around 1800 or so pounds. That to me would be a 1 ton f350 chassis. Any thoughts or documentation? Is is really a heavy 3/4 ton?

I've got an 00 EX V 10 4X4 with 4:30's. I get 11.5 in town, and around 13.5 on the highway. I have pulled a 16' trailer with a 4 wheeler on it (not much weight...) and the mileage dropped to about 12.5. If you pull a trailer, the 4:30's should perform better. Haven't seen or heard of 4:10's in the newer rigs.

ratio confirmed 3.73
I cleaned the tag I was looking at some more and it appears that the first part of it shows .73 the leading 3 must be under the bolt that holds the cover on.
So, Monsta was right all along.
The tag also referred to a s 410 b code which is where I got the 4.10 from. Thanks for all your help.
Now it gets complicated.
So, my X gvwr is 8900, - 7200 base curb weight leaves 1700 payload. subtract 948 for my trailer tongue weight leaves 752 lbs for people, fluids and cargo, minus the 44 gallon gas tank and not much payload left for inside the truck.
Next - since my gcwr is 17K, leaving 8,100 for the trailer. Since my trailer dry weight is 6993 I have 1100 for cargo and fluids in the trailer. Fluid capacity will approach 400 plus lbs so that leave 600 lbs of food, clothes, ice and beer.
I hope they over build these things a bit.

Your right, not too worry
I would be a happy camper for 10 mpg towing. Prior to this vehicle TT combo I had another brand truck and lighter TT and I got around 6 to 7 going from NY to NC. Could not keep it in overdrive, constantly running 3,000 rpm or better at 65 -70 in drive. Sucked the fuel so bad I needed a tanker truck to meet me to fill on the fly (ha ha). Put in a hypertech power programmer plus program and ran 92 octane and it got up to 9 and even 10 one tank coming back from NC to NY.
I have been doing some research on performance mods and been reading the forum. So that may be something I look into for a little better pulling properties and crisper shifting and throttle response. Some say even a bit better mileage. I'll have to figure my break even point for the cost of the programmer and premium fuel to how much fuel it might save me over time. Not a big issue but what the heck, if it mean 2 mpg better why not try it.

The frame on the Excursion is specific to the Excursion. It is based on the somewhat shared chassis of the it's F-series brethren.
They did NOT take an SUV body an bolt it to a pick-up frame.
And FWIW, the 4.10s are only available with the 5.4L gasser and select dually diesels. Too bad...I've always said they'd make a great ratio for the V10.

Monsta, more info please.
Do they give a 3/4 ton rating or 1 ton rating to the EX or due I use the payload of mine which is gvwr 8900- curb weight 7190=1710 payload and call it a heavy 3/4 ton?
My axle ratings are 4250/5250 = 9500. Why the 600 lbs difference between gvwr and gawr?
