Much to my delight, the new unit performs about the same as the old one, even with so much more weight to move. I am sure it burns more fuel, but I don't track that. An added bonus is that while the old unit had a somewhat unpleasant roar when working, the new one has a deeper rumble to it.
Class C RVs are built on a E350/E450 chassis and use a 2 valve version of the V10. Class A RVs ar built on the F53 chassis which is basically a medium duty truck/school buse chassis. It uses a 3 vale version of the V10. Short story, the 3 valve makes a lot more power. The 6 speed transmission helps also.
