Starting a Montana LLC to avoid some taxes and fees first.
Be careful with that. You don't say where you're from, but many states now watch for that sort of thing, and getting caught if you live in Colorado can be mighty expensive, probably true in many other places, too.
Regardless of price what are the highest quality brands/models in class A?s and C?s available in the 28-32 foot range.
How are you defining "quality?" I ask because there are many of the higher end units that, though they use better materials, still have their share (or more) of problems. You might mention why you want a coach that short -- sometimes intended purpose can make a difference in recommendations.
However, we could start with top end class A coaches such as Prevost bus mods, Newell, Foretravel, etc., where you're talking well over a million, perhaps closer to $2M. Or you could look at the upper tiers of Newmar, Monaco, American and some others. But few, if any, of these are under 40-45 feet. But some of them do have the shorter units, too, such as Newmar, Fleetwood, etc.
I don't know of any class C units that expensive (read top end), but there are a number of Super C rigs by Jayco and others. And Newmar is just coming out with a new Super C that even has air suspension, unlike most of the others.
However, whether new or used, price-when-new is a fair comparison of where a coach is in the overall material quality/features/amenities look at the market.
I'd suggest getting to an RV show, or at least to a large dealer or two, to see for yourself what you might be getting into. You can learn a lot very quickly that way.
