Greetings folks,
As you can see from my signature I own, not one, but two 6.0 liter diesels. My Excursion has just rolled over 100,000 miles and it has had problems with the turbo, the HPOP, and the injectors. The turbo and the HPOP were replaced under warranty some years ago and recently I had NEW injectors installed with no other issues. The Superduty in my signature is another matter entirely. I have had issues with everything from HPOPS to FICMS, to most all 6.0 problems. As recently as last week, the transmission seemed to just "come out of gear." The last time that happened I got to my destination, turned off the engine, and it wouldn't even click when I got ready to restart it. I had new OEM batteries, checked voltage and they were good.
Turns out the fan clutch had shorted and the transmission range selector was faulty. Apparently the PCM can "hold out" the fuel pump and starter circuits when an issue is detected. We are working on this as I am writing.
Now for the good part: the truck has a blown head gasket. My mechanic says that is going to cost about $4,000.00 to repair. I am not sure I want to pour more money in this truck. Also, I travel with a 32 foot fifth-wheel camper, so I need a truck like I have.
Here is my question: I am seriously considering a newer truck to replace both of my current trucks. My mechanic has forbid me to purchase anything older than 2017. What issues do you observe with this vintage of Superduty? Are they serious? If I purchase a new truck I may go with a 7.3 liter gas engine depending on what answers I get to these questions. Thanks in advance for your replies, Craig.

I was lucky enough to get one of the last 7.3L diesels made in '02. And kept it for 10 years. It wasn't problem free, but when I saw what my friends with 6.0's were dealing with, I was pretty happy. I sold the truck because we moved overseas. upon return, I ordered my current truck; a 2017. I have had more than my fair share of issues with mine, but it was mostly due to poor workmanship at a particular dealer. It started out when I was chasing a bit of a groaning noise at 70mph. This dealer did all sorts of bad work, breaking clips, causing electrical faults, low coolant, and a failed rear end. My poor truck has been in a shop for 8-10 months during the ~6 years I've owned it. Mind you, it's only got 33k miles!

But I think mine is a fairly isolated case as most others I know with this generation are still loving them! It would take a seriously modified 6.0 to keep up with these 6.7's.

Also, look at transmission variations. I can't be certain, but I think 2019 got the new 10spd. Might drive both and see.

One last word of advice...the used truck market is crazy right now. You might look into pricing brand new as it may be within a couple thousand of used??

10 speed transmission was introduced in 2020. I have the 6.7/10-speed combination and love it. The only problem I have had so far is a bad NOx sensor that was replaced under warranty.

I get about 11-12 mpg pulling my 42' 5th wheel (14,500 gross) at whatever speed I feel like.

I have seen some favorable reports about the 7.3 gas engine's towing capabilities. It will get the job done but does not have anywhere near the hp/torque and mpg that you would get with the diesel. You just have to pay an extra $11,000 to get the diesel. The engine itself seems like it is solid - most problems happen in the emissions system which, unfortunately, can turn the truck into a really expensive brick until the failed part is replaced. Stupid EPA mandated failure modes will put you on the side of the road before anything else.
