The newer campground directory websites (Allstays.com, RVparky.com) also have reviews, and it's always a good idea to check out a couple sources to get an overall idea of what the place might be like. I also like RVParkReviews.com because it's easily organized into a location database. But it's somewhat hit or miss on which campgrounds are included, since it relies on users to come along and share the information, i.e. there are a lot of campgrounds potentially not listed in any given area. That goes back to checking multiple sources when you are researching campgrounds.
