We are also life members and it has paid for itself a few times over. That said I do look at RV Park reviews or online reviews or Trailer Life directory to see how they rate. Many are very nice but some are not so very nice. We have used them only for overnight stops and that works pretty good if they are close to the highway. Doesn't make much sense to save $15 on a site if you have to spend $15 on fuel for an out of the way location. Just my thought.
