My understanding is that Caterpillar significantly raised the prices on the new reduced-sulfur engines and Cummins did not as much. Many RV manufactures went with Cummins due to the price increase.
The new Cummins engines are a bit quieter, have more emission controls and have less torque than the regular Caterpillar diesel engines.
Most bus and truck drivers I have talked to like the Caterpillar because it has more power. This scenario is similar to the leaded vs unleaded gas change a few years ago. More equipment was added onto the gas engines to reduce emissions.
I am running with a Cat diesel and did not change to the Cummins since it changed just when I was buying mine 2007 vs 2008 models.
I guess if you want more torque or less emissions would be the difference. </div></BLOCKQUOTE>
Yup the cat at 860 lbs of torque sure puts cummins to shame at 1050 lbs.
