99 is the mpg for all Fords I’ve been in. You only have to hit reset and go down a steep hill. It’s the norm. [emoticon]


You have a picture to prove it?
I have 1 for my sedan.
Bad news, 99.9 is end of the scale as for some time I was doing much better.

I am running the 6.2 Dually with a 4.30 axle. I am able to stay right around 10 mpg. The axle gear has something to do with mpg. The bigger the number, the lesser the mpg. Like one guy said, I didn’t buy mine for mpg, I wanted better pull going up hill.


Having run a lot of miles in 6.2 Fords. F250s, I can say your mileage is NOT the norm and either your reporting is, umm, optimistic, or you are basically hyper miling the truck.
Presume you’re saying 10 mpg with a big truck camper on. 10-12mpg sounds right driving empty.
Again, unless you have a bumper sticker that says “55 saves lives” and actually believe it!

I have a 2016 F250 with the 6.2 gasser with 3:73 and hall a Northstar TC650 pop up truck camper. On the highway at reasonable speeds, I get between 11-12mpg. In town, it is less. The performance is fine but mileage with truck campers is never good!

Anyone have real world HIGHWAY gas milage figures for a Ford Super Duty with about 3000lbs of truck camper in the bed? I’m specifically wondering about 2017-2021 F250 and F350 trucks with the 6.2 gas and new 7.3 gas engines. Reading online I see claims of similar or maybe only 1mpg less with the new 7.3 gas engine, but what about in the real world? (I know they have their place, but not interested Diesel numbers)


My 2012 6.2 gas flatbed 4x4 Fordor Ford at 100000 miles does 8-10 mpUSgal campering and 14-15 mpUSgal bob tail. Towing a 16 x 8-1/2ft tandem enclosed doesn't change it much except when the crosswind blows. Then 7 is totally achievable.

These MPG threads are totally dependant on the driver and his habits..There are some here that could make a VW Beetle get bad mileage.LOL

My last two 7.5 Fords(460) have both gotten 10mpg+ loaded ready to camp because I know I have a zippy/gas guzzlin' engine if I do not keep my foot out of it..I easily get 13+(never 14 yet) empty and 10+ with the TC on and the other was a Class C..LOL

I would not hesitate to get either of Fords engines or the Chevy 6.0 like my son has that's been bullet proof..

Keep in mind all the F350 are ten speed as of 2020. So comparing 2017-2019 to 2020+ will be slightly different with ten speed having the advantage.

I guess 10 speed can help in city and mountain driving.
My dually spend about 95% of its life on the highest gear and highest gear usually is the same regardless how many other gears you have.

I will be picking up a new 2021 Ford F-350 dually 4x4 in less than two weeks.
It will have the 7.3 gas with 4.30 rear end. I will be putting an 2013 Eagle Cap 950 on it.

I is too bad, and always the case, that aftermarket shocks/sway-bars are not available this early in the model year.

I will update the forum as to how this truck performs.

This truck will be replacing a 2013 RAM 3500 4x4 dually.

Sweet. I doubt you will need any suspension mods. Payload on that truck is crazy! Of all the mods I have done, sway bar was the least effective. You should be fine.

There are no changes from 2020 to 2021 so should be easy to find aftermarket parts. I wouldn't expect that you'd need any mods for that camper.

I also recently went to a 7.3 gas after owning diesels for ~12 years, mine's a single wheel with the Tremor package. Haven't had the camper on it yet. Don't really expect great gas mileage but not really a factor in my decision to go gas.
