Crude oil price is dropping fast and gas prices are following it, not a great time for Ford to go EB on the Super duty, it will likely happen in the future but not likely now. If Ford has played its cards as correctly as it has with the 3.5 EB F150 and 6.7 Diesel Super duty they will have a much more powerful gas engine in the next generation of Super duty truck engines.... Although the unpredicted low oil prices weren't necessarily in the cards, should be interesting to see what they do.

I know multiple Dodge Cummins owners that have claimed their trucks can get well over 20+mpg but if you're friendly, persistent and ask the correct questions eventually they will admit they have never actually got anywhere near 20+mpg but think they can... And generally get really quiet when I mention my V10 can get 13/14 mpg at 60mph HWY. and if they stick to their mpg claims I'll start talking about what I tow with my truck... That is always a talking subject changer.

I have 2 family members that have older 24v cummins engines and they absolutely get over 20Mpg, I have experienced it. they use a lot less fuel than my 5.4L truck at 14/15 mpg highway. The trucks still run really well with over 200K on them, but the body's are starting to rust away.

My 12 valve cummins gets 21 regularly. My old '06 5.9CR would get 21 loaded or empty. My 2010 6.7 Ram got 12 loaded or empty. The cummins can do it but not on the 6.7 unless it's deleted.

So reading this in retrospective I'm half laughing here.. I've been toying with getting a new(er) truck to replace the Navigator and '90 F250, and have checked out Ford, GM, and Dodge (I refuse to go with their "RAM" change.. still a Dodge Ram for me).

For all the whining about Ford, look at GM where the only HD gas engine has less torque than the base V8 half-ton, add to that you get the 6 speed in the HD vs a 8 speed in the 1500. Also the 1500 offers the 6.2 which blows the 6.0 out of the water in every way.
At least Ford the 6.2 gets you more torque than the 5.0.

(6.0) 360 hp @ 5400 rpm and 380 lb-ft of torque @ 4200 rpm

(5.3) 355 hp @ 5600 rpm 383 lb-ft of torque @ 4100 rpm

Ford at 385/430 vs the Chevy 6.0, not even comparable.

Ford is the only offer with a OHC in a HD truck (Toyota & Nissan don't make true HD truck comparable to the Super Duty, though the Titan XD is supposed to dabble in that field).

Dodge and GM both are at 2 valves, pushrod. Even Bentley's $300k+ cars offer 2 valve pushrod engines!

I'm an automotive engineer, and I'd never make 4v/3v/2v/5v (Audi), 1 cam, 4 cam, 8 cam, whatever a primary factor in buying a car/truck unless there was a specific example... I just prefer whatever is best for the application, and overall the best engine available.

I looked specifically for a 03-04 Navigator because of the 4v, not because it was 4v, but because my research indicated that it was the most reliable of the 5.4. Note the 05-06 with the 3v SOHC actually has better numbers than the 03-04 DOHC. In the case of the 5.4 I wanted DOHC because it was just an all around better engine.

However, all else being equal, I'd have preferred the Escalade's 6.0 LS engine. But I liked the rest of the Navigator's offerings better.

Now if I get a newish truck I will almost certainly get a Dodge simply due to being the only manual transmission offering on the market.

Having just come out of a 5.7 Tundra, I can attest that the Ford 6.2 is a sweet motor. My last 3 trucks have been Toyotas (2 Tundras and 1 Tacoma) and their reliability is unquestioned. The 5.7 Tundra motor is a nice piece but the mileage is not great (12-13 in town, 15-17 highway) and really didn't have the top-end power one might expect from a 4V design. What truly surprised me was the 4.0 V6 Tacoma. It was an access cab, 4x4 with 6 speed manual I bought during the height of the recession, in hopes of 20+MPG....I never saw over 16 MPG, even on 100% highway driving....so I went back to a Tundra for the size and power.

I was looking hard at a Tundra TRD pro but it is basically a SR5 with some suspension bits.....for $50K+. I bought a 2017 F250 CC FX4 Lariat 6.2 for less than I could have gotten a TRD Pro as they are allocated (you can't order 1), and dealers, for the most part, are not discounting them. The SD Lariat is a much better equipped vehicle as well.

I have owned a lot of Ford vehicles but they lost me in the late 90's, early '00's with their QC (I had a '01 Bullitt Mustang and while I loved the car, the build quality was laughable). I bought a '15 Mustang GT 2 years ago and no issues so far so I hope this new SD follows suit....so far, I love it.
