Cummins X15, what's the word?

Doesn't matter what engine you buy if your gonna take it to the dealer for everything. The end result will be the same, a lot of money spent and recurring problems.
One of the biggest reasons we all own cummins here is so we can work on them ourselves. They aren't really superior in any other way except maybe better fuel efficiency but that's debatable.

Not sure what you mean by "catastrophic failures" but if your referring to the fuel pumps, that can be easily avoided by replacing the guts every 400K miles.
If your referring to chewed up cams, that can be easily avoided by changing your oil based on your fuel mileage, installing a bypass filter(if truck is not demandated) and setting the overhead about every 200K.
If your referring to dropped liners that can be easily avoided by not lugging the piss out of the engine running it below 1500 rpm all the time and DEFINITELY NOT LETTING SOME IDIOT PUT A BAD PROGRAM IN YOUR ECM.
although if your gonna use the stealershit network out there you'll have to keep stock programming anyway.
All the new engines need constant maintenance and that isn't going to change.
