The Cummins 5.9 in a medium duty truck is a 300,000km engine (186,000 miles) and it usually need a rebuild. The C-7 Cat is good for 500,000kms (310,000 miles) before it needs work.
The Cummins is a industrial engine and thats about it. Works for running compressors or generators etc.
When people say the 5.9 and 6.7 is a medium duty engine thats a frigging joke
The 8.3 ISC is a medium duty engine the real Cummins engines don't start till the L-10 M-11 ISM. The best Cummins engine made was the N-14 but the 350-400 Big Cam was good the 444 was junk. The ISX isn't that great know a few people that don't like them. The Cat 3406 is the best engine Cat made the 3306 was good too but the 3406B and E model were the best truck engine.
The 5.9 and 6.7 are tinker toys a throwaway engine nothing special.

I work with gravel trucks so I have experience with the 400 Cummins and the 3406 Cat and some with the N-14 Cummins.
I have been around trucking to know that the 5.9 is way out of its legue in a medium duty. The 5.9 Cummins is one step above a gas engine powering a medium duty.

Yes i have talked to some guys that have around 500,000k with a cummins in a pickup truck. One guy has a early nineties, and the other guy has a late nineties, and I know them both personally. A few of the other guys I have talked to were just out on leases and whatnot and it was smalltalk.
One thing nice about a cummins too is the rebuild aspect of it. From what I know they are considerably cheaper to rebuild then a powerstroke.
Kenworth, we have an n14 in a kenworth of ours at work, and yeah, that engine is great!

5.9 Cummins a "throw away" engine? I can't buy that even for a moment. The Dodge truck it came in may be a throw away truck, but the engine is a keeper. I've got a 1993 CTD and a 2003 7.3L PSD. I can only hope the PSD stays as trouble free and reliable as the Cummins.
