When it come down to longevity on a vehicle that spends its life pulling a heavy load diesel will win vs. a gasser.
If we are talking daily drivers gasser are fine and there is little longevity inequality but if the engine is under load the entire time diesel wins.
Our 5.9L Cummins rollbacks would get rebuilds around 300,000. We had one Duramax with 300,000 but it was so low on compression is only made about 150 HP. Another Duramax in a TopKick 5500 was done at 200,000 and rebuilt costs are high enough it didn't make sense to rebuild that one.
Meanwhile other companies running V10s in the "Autoloaders" (aka Repo trucks) are going 500,000+ without rebuilds. And being a V10 they can sneak into your driveway without waking anybody up;)
I'm at 367,000 on my V10. Just did its 3rd tune up. About 200,000 of those are towing miles. Typical load is 22,000 combined, occasionally go over 25k.
