I have 24v 5.9L in my 25' former bookmobile. It was specc'd with a 10KW Onan genny and 16 floor-ceiling 3/4 Maple ply bookshelves loaded with books. The bus cost them north of $160K. It was their 3rd Bookmobile with the 5.9L. It was not light.
Everyone keeps telling me how underpowered it is, but have yet to see the effects. Have not gone through the mountains yet, but probably wouldn't drive through them at 70 mph, even if I could.
Most of the comments on the Board about Cummins engines are from people who never owned one. They think the 12v=24v.
It's more a function of the transmissions. Diesel trucks did fine with low-horsepower engines for decades, still got up the big hill and dumped the dirt.
None of the Dodge stuff will work, unless you replace the harness, injection pump brain, ECM, sensors...I forget what else.
Cummins shop could turn-up the settings a bit, but they are dealers, aka jagoffs--at least Chandler Services is.
