The Cummins is a medium duty engine in a light duty application. The PSD is a light duty engine in a light duty application.
No to say that the PSD is junk, I don't think they are, at least not the 7.3L. I wouldn't touch a 6.0 or 6.4 with a 10ft pole.
I've run a lot of V8 diesels on up to the Cat 3208. I prefer the I6 design over the others. More torque vs. hp, too.
The 5 and 6spd trannys all have their quirks, but what piece of equipment doesn't?
6spds shift hard for some, but not others. I've driven a 3rd gen with a NV5600 before, and I liked it.
Only driven 1 truck with a NV4500, but it was in a GM truck, and they are slightly different. Liked that one, too.
The 5spd has the 5th gear nut issue, but they have a fully splined shaft for them and IIRC, a newer style nut. Works MUCH better.
