Someone said that a million dollar RV is not a camper. I must respectfully disagree: although I have a tiny trailer and greatly prefer boondocking, I say "to each his own." To some people (some of whom are close friends of mine), staying at a luxury RV resort "campground" is a great adventure, compared to their usual Ritz Carlton experience. Bravo!
In the same vein, folks in truck campers sometimes smile when I describe my so-called "adventures" -- we take our trailer (slowly) on dirt roads, while truck campers climb rocky cliffs. So I can't judge what other people do.
And just to stay on topic, I nominate Buckeye Campground in the Eastern Sierra near Bridgeport -- high altitude, very cool and quiet, great views of the mountains and the valleys, great hiking nearby.
