You are complaining about a 15 year old truck with 116,000 mile with an issue that started about 44,000 miles? How old was the truck and what was the issue.

The issues started back years ago well within the 100K warranty.

Totally understandable, based on how the corporation handled it, presuming that's the whole story (problem, not fixed, fixed wrong, not fixed, caused bigger issue, not covered).
You seem like a person who knows other people with vehicles with issues from time to time (we all do, right?) and cruises the web reading people's stories about their vehicles.
Unfortunately your issue is not mutually exclusive to Chrysler and you may expect to be upset at another manufacturer for a similar issue. Don't be overly optimistic about other mfgs.

"Use all the time, or it will carbon up.

Is that a real fact, or myth?"

It's a myth. VVT's go through the same motions everytime you punch the skinny pedal as they do when the e brake works, except in reverse.
Using the exh brake will not do any more than just driving it to prevent the turbo vanes sticking.

Now that is true of butterfly valve exhaust brakes. If they remain static for alot of hours/miles, they could cake up and stick theoretically.

I believe the late 5.9’s were bulletproof (dodge spec’d fuel lift pump issue already resolved), so I don’t get your complaint with Cummins especially since by your own admission it was a technician's ineptness that caused your issue... My 2004 5.9 was amazing, as was my 2007.5 6.7 , though I did have first year (dodge spec’d) 6.7 bolt on emissions equip issues...In contrast, my 16. 6.7 has been trouble free thanks mostly to DEF treating the emissions chemically, primarily within the exhaust tract rather than underneath the hood via massive amounts of EGR...

I very much prefer the uber minor inconvenience of DEF...

According to TCM, for 2020 Ford has ‘quietly’ done yet another diesel redesign (block, heads, injection, etc) their 6.7 Diesel...Huh?? Seems that each generation is fairly short lived - why is this??...Dealer service depts must spend lots of time doing re-training...Nice trucks no doubt, but every since it was reported that they have to remove the cab to work on the engine, not really my cup of tea...

I agree. I skipped that whole generation between 2006 and 2015. I waited until Def was proven (but my 15 did get recalled for exhaust parts replacement.

running from central FL to Central PA round trip I use around 2.5 gallons of DEF running 70 mph towing 14' box trailer. that is not even a penny per mile

I don’t think TCM would generally be considered a top source for Fords, but any way. They take the cab off because it’s actually smarter. It’s designed to come off. If you do some research, you’d know that it’s actually only 45 minutes for an experienced Ford mechanic to lift the cab out of the way. That makes easy access to almost impossible to reach items otherwise. Unless you compare on/off timings of several jobs, you really don’t know anything about why taking the cab off makes sense.

If you’ve been following along, Ford will be introducing a total redesign 7.3 gasoline n 2020. GM has a redesign of the diesel and gasoline engines, and Ram just redesigned their 6.7 for 2019.

As far as DEF generation goes, it’s certainly better than the other heavily modified engines to improve emissions, but still not anywhere close to as troublefree as the engines without the DPF or the DEF/DPF combination.

The Cummins VVT turbo uses a sliding ring for the exhaust brake. I use mine every time I drive the truck. That is the rings only function, to that point even in the Fords and GM, why not use it all the time to save on your service brakes.
