Yep, 2017 SD w/6.2L and 3.73s.

The MPG is interesting between the older -'16 and updated '17+ 6.2l.
Ford squeezed out a little more torque and hp and adjusted it to peak at about 3800 RPM instead of 4500 RPM. They also put a model/motor specific 6R100 transmission behind the 6.2 only in the F250s.
Looking at the gear ratios of the 6R100 compared to the standard 6R140, 1st and 2nd are slightly lower by about 5% but the higher gears are nearly identical. The 6R140 actually has slightly higher 5th and 6th overdrive gears.
Anyways, my point is, the '17+ may be showing higher fuel mileage but I think it has to do more with the adjusted engine as opposed the the transmission gearing.

I am currently in the shopping phase for a new truck, favoring the F250 6.2L gas, curious about the gear ratios 4.30 vs 3.73 which is preferred and why, is one going to provide better torque and less mileage and vice versa

4.30 is the preferred gearing for maximum torque and towing.
The 3.73 gearing is no slouch either for towing and general driving.
MPG is kind of not a deciding factor with the 6.2

Agreed!
The 6.2 with 4.30:1 locking axle is really tough to beat with anybody's gas engine. Anbd, as both 5th and 6th are overdrive gears, MPG shouldn't be horrible. I bought the F250 to do a job, and mileage is not a big consideration, unless of course, it is your daily driver and you have a fairly long commute. I definitely wouldn't have the 3.73 axle except on the diesel, which has gobs of torque...althopugh I'm really pleased with my 6.2 gasser.

We had a 2015 f250 6.2l Lariat with 3.73's and factory 20" wheels that we loved. We towed our new 9500 lb (scale verified) 2,000 miles on the flat lands of the Southeast before realizing we would be better off with a heavier truck. The mileage of 8.5-9.0mpg was acceptable. Had we had 4.30's with the maybe smaller diameter 18" tires, we might have been well satisfied. I can't say enough good things about our 6.2l gasser. History may prove that it was the best all-around truck we ever had.

The difference is that in the Ford SD trucks you get the 6.2L, 6-speed and a 3.73 rear end while the GM HD trucks you get a 6L, 8-speed and a 3.42 rear end; tow ratings are about the same. The 6.2L GM engines are in the 1500 LTZ and Denali series trucks with the 8-speed (with a 10-speed coming in 2019) and either a 3.23 or 3.42 rear end (9200 or 11,700 tow rating, respectively) . What I am surprised by is that the Ford 6.2L gets such poor mileage off the lot but gets improved gas mileage with use. Is there a problem with the truck's computer? The gearing should give you a little bit poorer mileage than the GM trucks but not that much. Something isn't quite right.

Mine has the 6.2L, 6 speed, 4.3 . There are multiple configurations from Ford.

During the time I owned mine, the lifetime average mpg was 11.1mpg over a total 29,800 miles driven. Approximately 9,000 miles was interstate towing, the rest was mostly around town and short 2 lane hwy trips. I’ve read reports that the 4.30’s might have actually helped reduced low speed down shifting and improved mpg. Despite the mileage, there are many benefits to owning a truck like this. Under tow, Mine did not do hills and overpasses well at all and that is with me constantly using the manual shift mode. The switch to diesel was primarily a safety consideration because I was constantly paranoid that I was going to be rear-ended when the rig would drop below 50mph on slight hills and overpasses. Maybe the improved 17 and later models perform noticeably better than mine did. If you plan to tow weights over 10k lbs, I strongly recommend 4.30 gears or switch to a diesel. I’ll be watching future developments of the makers closely because I’d much rather tow what I have with a gas engine if I can get an acceptable to me level of performance.

No sir...
GM HD trucks you get the 6.0l and a 4.10 gears with a 6 speed transmission...and the Ford SD offers either a 3.73 or 4.30 gears with the 6.2l.

Both gears will get the job done but if the purpose of the truck is to tow, then 4.30 are what you want. MPG's are irrelevant in a truck like this imo. Stock you will turn about 200 rpm more in 6th at 60 for example but you have better low end grunt. If you plan to upsize tires then 4.30 is also the way to go. I wish 4.56's were an option.
I have yet to find a pass here in OR I can't pull at whatever speed I want. I haven't found the need to use manual mode but I do lock out gears so it won't upshift. I like to spin 3500 to 4000rpm to hold 55-60mph depending. I have found myself easily going past 75 and still accelerating. The 6.2 is a beast...

These prices are way out of control on new pickups. One of the worst investments a person can make. I'll stay in the 2015 to 2017 range.

Don't despair. Mine got horrible gas mileage when it was new; also Minnesota January. I was getting 11.5 mpg. I think it is the differentials, transfer case, etc are VERY tight. The truck would not coast at all. Let off the throttle and it felt like you dropped an anchor. Mine improved immensely after we used it towing our 5er on a 5,000 mile trip. It really loosened up the drivetrain. HUGE difference on the coasting. I feel my mileage is excellent for such a heavy truck with 4.30 gears.

If you're buying a vehicle as an investment, you're doing it wrong.
A typical vehicle purchased to be driven and used is a depreciating item the minute you sign the dotted line.
While pickups these days are extremely expensive, buying slightly used will help curb the initial cost. My '16 F250 had 33k miles and was 71% of the MSRP sticker price. Had I bought it new, I likely would have paid about 85% of MSRP sticker price.

As others have noted, the 4.3 is the way to go. Yes, for what I read, you might lose about 1-2MPG. If you want further input, and info, go to the Ford Super Duty forums. I learned quite a bit from that forum before I made the decision of 4.3 over the 3.73 and gas vs diesel. The issue I ran into and was mentioned in the forums much to the chagrin of many was the difficulty in finding trucks with the 4.3 gears. Many on the forums were buying 3.73 then paying for the change to the 4.3. That was last year, so not sure if it has gotten better.
I was originally looking for an optioned Lariat but the only truck near me and that was an 8 hour drive away with the 4.3 was a Platinum that I ended up buying. It's my first Ford and so far so good. I really like the truck. Good Luck! I think you will also really like it.

Hold out for 4.30 if you can. My 2017 with 3.73 and 35" tires does fine, but the 6 percent grade of a mntn pass I go over a couple times a year works the 6.2 pretty hard. Pulling about 11,000 lb (loaded) toyhauler.
I got a great deal on my truck, $39K, but if I could go back I might just wait for one with the 4.30.

The combo in my signature does great with the 3.73s. Throw a 5 Star tow tune on it to better manage the shift points.

Almost swapped 3.73's for 4.56's in my 2015 F250 6.2l

I explored options to change my 3.73 gears to 4.56's. The cost locally in a 4wd shop was $2200 for both axles. The local Ford dealer wanted $3200 for 4.30's and would have provided some warranty. There's lots written on the Ford forums about this. Owner feedback on the results after the swap was mixed which is why I decided to move to a diesel.
