PS 6.7 ?
Since watching everyones favorite PS person, yeah trying to be funny. Daves auto in Utah. Kinda got me into a bit of a study on this Ford creation. So where is a good area on this site to see all the issues with them?
My first impression is they sure could have had something fairly good, but really missed the mark in a huge way. I guess its the now modern way to not try, seems that way with everything in the automotive world now.

The reliability of the 6.7 is head and shoulders better than the 6.0 or 6.4. Early issues with the 6.7 were mostly resolved by 2015. Most of that had to do with the turbo and some radiator issues as I recall. I started following the 6.7 when I bought mine new in 2017, so I don't focus much on the 2011-2016 years. 2017+ issues tend to be with the emissions.
Dave has his own biases. As I recall, he wants to sell his secret sauce. But otherwise, he seems like the type of mechanic that I would prefer to take my truck to.

The CP4 should be a recall, and dealer install of the DCR. The engine design is horrible, just like other horrible designs some work okay and some not. They got a few things right on them and many things not so.
There is huge room for improvement, but that will not happen, they cut all the corners they could, saves the manufacture big bucks, and they never pass that down.

There is a YouTube video from Dave's in Utah on a 2017 6.7 that had a lifter start to go out at 922K miles and still was using the original CP4, which looked just about brand new, as he had been using additive religiously and overdosing as I do as well.
I am just trying to understand what you're basing your observation on that the 6.7 is a "terrible design" on... I'll wait to comment further...

Use clean treated fuel and regular oil and filter changes and the engine will last longer than you will keep it.

Not to start a Ford v Dodge debate but the rust buckets around here are the RAM trucks. The frame on 2017+ trucks are still steel but the bodies are aluminum which is going to last a long time.

Any vehicle here can become a rust bucket here if care isn't taken to prevent it. I removed my fender flares a few years back and found bubbles underneath them. As a whole, Chassis Saver by Magnet Paints, sticks very well to weathered metal and rusted metal (remove all loose rust). My goal is to have my 16 coated, the whole truck, with Bullet Liner. The frame is solid. It was coated with Ziebart but the Carwell Products oil I have sprayed annually keeps it in good shape. I do have some minor rust in spots and still have to get under the passenger side this year like I did to the driver's side in 23. I'd also like to remove my bed and deal with the minor rust on the bed channels I see on the ends, but also to inspect the bottom of the bed as a whole. The rockers are solid as are the cab corners. I plan on doing a thread in the future on my battle with corrosion on my truck.
So yes, it's a chore to own a vehicle in the rust belt but if you don't want it to rot out, it's a necessary evil to stay on top of corrosion and keep it under control. But I agree, the aluminum bodies will probably do better than us steel body guys...

My advice to you would be to find someone spraying vehicles with Woolswax as they make different products for different areas... or maybe you already have it done.

I have not yet. I have a buddy who swears by a few cans of rustoleum.

It's better than nothing, but it doesn't get into nooks and crannies like Woolwax does.
