I have 2015 eco diesel with 47k miles. The computer shows 32k towing a 28 front bedroom ATC toy hauler. Most of this is a tough run to Oregon and N Cali.
I recently needed the egr cooler replaced, but that's it for issues. It pulls like a mule, no drama, I seldom over get over 2500 rpm with the 8 spd ZF and 3.92 rear end. Full air suspension is incredible. Mileage is the best I've ever had, and I will never go back to normally aspirated towing at altitude.
That all being said, I have the factory extended warranty to 120k miles. This engine can achieve very high numbers of reliability, some over 300k. But, it can tank quickly and most are using a tune to by pass the egr. I'm stock for lots of reasons, mainly because tunes are illegal.
Would I buy another? In a heartbeat. But only if towing is a requirement. That's where it shines.
