Not knowing how you envision using your class C. Or if you are open to used units. It is hard to make suggestions. I know nothing about new ones. But what I have in my sig below is my second class C and the best I have had. The Chevy 4500 is hands down the most fun to drive with stock suspension. The house is well made and has little detains like all the holes going through the floor are factory sealed. The only thing I miss is dual pane windows.
Never purchased a high end class C. But Bigfoot & Coach House come to mind.
