In all frankness, it's sounds as if you have already formed the image of what you want to find - rather than making your journey one of discovery. Are you seeking to learn what is - or confirm what you expect it to be?

Anyway, why an RV? Just rent a cheap car, buy a cheap tent and sleeping bag, air mattress, an ice cooler and small portable gas grill. There are campgrounds all over the place - and in Sept./Oct. they are uncrowded.
If you do this, treat yourself to a budget motel every third or fourth day for a soft bed and a private bathroom (and to do your laundry!).
And come with an open mind - not pre-conceived expectations!
