I bought mine used over 20 yrs. ago. I have traveled from west to East and Canada resorts. When I sell it, it will be as good as the day I bought it. Buy used and get the Gold or Platinum. Not really up to date on the new memberships.
Best thing I ever did. But one thing to keep in mind. You have to use it to make it worthwhile.
I figure a 10 day use a year is the break even point compared to paying other rv park, KOA etc. at my locked in rates.
Some parks are better than others and you learn your favorites.
I love my yearly early spring 2 week stay in Verde valley, AZ. every year.
