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.

I have the 3126 in my 2002 Itasca Horizon - and it's the early version of the Cat C7. The C7 change was partly due to the emissions stuff and I'm glad I don't have that - as the MPG suffers.
My 3126 now has 92K miles on it, and if I'm not towing anything and keep the speed to around 62mph I do get 9.5-10.5 MPG (also with no headwind)
Towing I usually get around 8-8.5MPG if I have my 33' long enclosed trailer.
I really wanted to get the ISB engine, as they were known for good MPG, but the coach I found had the floorplan and price that was nice, so I got the engine I got, and it has performed well for me as I bought it with 24K miles.
