There are publications that rate campgrounds such as Trailer Life and Woodalls that some RV'ers use to guide them along their trips. However some campers find that what is a top rated park in the book isn't to them. For example a small ma & pa operation might get a low rating in the book but be a 10 to an RV'er because of the friendliness, cleanliness & woodsy country atmosphere. Check out www.MyRVparks.com, a free online campground guide that also lists fun activities & special events at RV parks all across America. www.PassportAmerica.com also lists all of their parks online with detailed information.
