This is the iOverlander map for the area around oaxaca. If you had the iOverlanderr database installed on your Garmin or smart phone and searched for listings near Oaxaca, all those entries would be listed along with description of the places. On smartphones, photos and recent checkins would also be shown.
BTW I have the Churchs book and still use it on a regular basis despite last time wasting a fair bit of fuel and time travelling to places that were closed. That it remains a resource is nothing to do with it being up-to date which of course it is not, but because nothing much has changed in all those years except that many RV parks have just got more and more decrepit and the owners don't know when to pill the pin.
