If I had some way to prove it I would bet most people driving diesel spend more time above 90% of redline than gas engine drivers do.
Why do you think that? The only time I see higher RPM is with the exhaust brake when loaded heavy, then I would agree the revs get high when its steep and I am heavy. Other than that, I would completely disagree.

Don't get me wrong I understand that how the gas engine makes its power.
I still don't want to listen to it scream for the entire drive.
In time the noise wears me out....LOL
How much more sound absorbing is put around the diesel?

Honestly, its the exhaust brake and low rpms of the diesel that keep me inclined to buy another diesel when I upgrade this truck in a couple years.
I have a kinda different look at this idea.
Has anybody seen a side by each comparison; Same gears, engine size load, exhaust brake on diesel and spark fired with closed throttle holding back on a down-grade?
Then think about this part. Something not involved in normal engine control must happen for the exhaust brake to began to slow vehicle. A bad electrical connection, no engine ******. OTOH, the gas engine, closed throttle is the default, engine braking will work even if engine will not run.
You’re really being a try hard here. Maybe time to step away from the keyboard and get out and enjoy the spring foliage and flowers!

Maybe I'm more used to real screaming rpm, from years of riding crotch rockets? My current Yamaha FZ1 redlines at 11,500 rpm, and while it does have an exciting scream, it is very smooth running. First gear at redline about 90 mph. It has 5 more gears to go! Due to factory exhaust valve tuning, it will handle 40 mph in 6th gear nicely. Top speed 170+
The Ford 7.3 makes good HP and TQ, at lower rpm than the 6.2, and many other gas engines as well.

3.5 mile hill? If you plan to go anywhere in my state, California, you will need to go over more than a 3.5 hill. Even if you want to get out of California, you're going to go over a mountain. I see so many folks crusin along on the eastern seaboard and I get jealous!

Well, I've been looking at those 7.3's. Holy ****! They are some nice looking trucks tho. I wonder if it would be possible to put that engine in my truck. My Pop put a 327 into his 1955 Willys Wagon but I do not remember what transmission he had.

I've found gassers in in the 4000+ relm to be just a noisy and obnoxious as a deezal in the 2500-3000+ rpm range. Depends upon the how far back you go 70's vs current models.
Elevation hurts non forced induction motors be them gaz or deezal! Put a low boost hp gain super charger on the 6.2, that would wake it up at elevation.
more than one way to skin the cat per say. just takes $$, and thehiw do you want to fix the issue.

Hi,
I had a 400ISL on my prior RV, so understand and appreciate diesel engines. We have a 7.3 with 10 speed and 4.30 and it is fine for our 15K fifth wheel. About 10K miles, mostly in California. The tradeoff is 3,500 to 4,000 rpm on hills (perhaps 2% or 3% of towing) versus better operation and ride when not towing (about 45% of miles for us.) I understand why some like diesel engines, but for 15K or less, this is a solid option.
Best,
Charles

Finally a gasser post with realistic numbers.
Gassers tend to rev in the 3500-4000 RPM range diesels generally do not exceed 2500 or so. Ultimately that is the sound, performance, comfort, relaxation difference. It's a different experience at lower RPM

Anything is possible if you throw enough money and parts at it. It definitely won't be plug and play. Not even close to worth it for the incremental power increase.

The cost difference makes is a wash when you factor in total ownership cost. Why not enjoy the diesel performance advantage?
Seriously, get a spreadsheet out and punch in purchase cost, fuel economy, maintenance expenses, DEF and depreciation/resale.
If the difference is material to you, you probably can't afford to buy either one.
