A couple of years ago we spend the winter at Outdoor Resorts Motorcoach Resort in Indio, California. Talk about "the other half". Our brand new 40' DP looked like something the cat had dragged in.
Not only were there >$1M coaches everywhere you looked but most were sitting on their privately owned sites which (at the time) were selling as high as $1M. There are a lot of people out there that have been much better at making money than I have!
