2009 Monaco Dynasty Regal IV with 500hp Cummins

We have an 08 Dynasty with the smaller engine. They are great coaches. Much nicer than the Dynasty's being produced today. None of the big coaches get good fuel mileage. Asking that question either means you should be looking at something smaller or you will get all kinds of answers that will state anything from 6 to 8. Mr. Mark's 7 is very close to what we get. I have a heavy foot and tow a 6400 lb. PU. A smaller car would probably help!
