Why would anyone expect an engine, although newer, with 2 less cylinders but a larger displacement, to get noticeably better fuel efficiency? Especially so in something with the aerodynamics of a brick like a heavy motorhome. No such thing as a free lunch.
Yeah, that was kind of my thought as well. I had a chevy 454 in a 3500 Savanna Van back a few years ago, and my gas mileage never was above 10mpg. It went down to 7-8 when I was towing my 12,000 pound trailer. There is no free lunch. As someone in an earlier post said, good gas mileage and RV should never be used in the same sentence.
