So Jack, you're saying that the coach we most want to purchase, from an interior point of view, is in fact a '07 chassis? And if that is the case do I want a '08 chassis for any reason other than the "mental satisfaction" that it is a '08 chassis?

If all things *except* the exhaust through the roof are equal than I don't think it's a deal breaker. But: if there are indeed chassis improvements that would change the complexion of the deal for me.

I currently own a '07 45' Country Coach so the move up will be substantial in all areas. However as we plan on doing 15k+ / year in road time for the next few years, I don't want to make a deal solely based on the interior of the coach.
