I have the 3126-E 330hp 860lbs of torque Cat engine on mine. I pull a Honda Pilot EXL which weighs 4400lbs and I get an average of 8.0 MPG.
I have 49K miles on my coach now and it seems like that engine is just barely breaking in. I just got back from a long trip and it was running great with all kinds of power going over big mountains. So it is a very good engine in my opinion.
I think you will like your Crescendo DP. But you will have some adjustments you will have to make. Don't care if it is a 750K dollar coach, they still have the same problems as anybody else (except) they like to keep it quiet because they paid such a large amount of money and still have the same problems everybody else has. Too much pride!
I saw some Crescendo coaches two years ago at the FMCA rally in Indio, California and they looked like a lot of coach for the money.
Good luck and go out an enjoy it.
