SOOOOO, where will the Cummins land???

That's a good question.

This engine was initially designed for the medium duty cab-over and delivery truck market which it has had some success. I would even wager that Cummins has sold more ISV 5.0L in cab-overs/delivery trucks than they did in Titan XD's.

Was wondering what other applications it was built for. Poking around the internet didn't find anything outside of Cummins website and it mentioned pickups only...of which Nissan was the only customer.

Cummins may even have an uphill fight in the medium duty arena. I recall reading a fire apparatus manufacturer, was either Pierce or E ONE, is offering the Ford 6.7 L diesel in a custom pumper as an alternative to the Cummins engine options offered. Is the Ford engine less complex or less trouble prone from an emissions standpoint. Cost savings over a comparable displacement Cummins inline 6?

Not really. The last conference we had from Cummins executives showed a 75% market share in the medium duty market and shipped a record number of engines the first half of the year. This does not even include the engines they build for other manufacturers like the PACCAR PX engines which are re-branded Cummins ISB and ISL engines.

Cummins or its re-branded alternate is also the only diesel engine option in most medium duty school/shuttle bus, refuge, and van truck applications for almost all of the truck manufacturers. If you ever see one of these vehciles, there is a 9/10 chance that there is either a ISB or ISL under the hood.

The reason why Pierce moved to the PSD 6.7L might be due to packaging. It is a lot easier to fit a push rod V8 in a tight space than a tall and long I6 with a turbo. They are essentially the same width due to the turbo and intake on the Cummins, but the push rod V8 PSD is shorter in both length and height.
