I am still using "Trailer Life Directory Campground Navigator 2010." That date "2010" is significant because that is the very last version of this great planning software that was produced.
I have the "replacement" entitled "RV Plan and Go 2013." The mapping module seems almost identical, but the campground information is largely missing.
Still, I wouldn't do without my "Campground Navigator." It is for advance planning on home computer, or on the road planning with notebook in the RV. I use it for every trip I make. I wouldn't think of leaving home without it.
It is extremely regretable that Good Sam/Trailer Life chose not to support an update working with the software company "Undertow."
I would still recommend to anyone interested in planning an RV itinerary to get one of these programs if at all possible. Old CD/DVD versions may be available online.
