400hp 9.2ISL Cummins or 400hp C9 Cat
Pros and Cons please and do realize that some of this stuff is like arguing Ford vs Chevy. Thing is, I'm not even in the ball park when it comes to Diesel power.

When I said my CAT was louder, I meant standing next to it outside while it's idling. Granted, most coaches are newer than mine, but I made the same observation on the Ford pickups my neighbor had. He is a contractor and bought a new Ford pickup every year. When he went from the CAT powered one to whatever Ford used next (Duramax???), it got a lot quieter idling to warm up in his driveway 7:00 am every day. The CAT always sounded like it was about to throw parts out the side of the block. The 3126 in my Sahara has a similar sound.
