We found Moon River RV Resort through the Good Sam Club.
The campground has big shade trees for the desert (finally some greenery). They do not block your signal, due to the fact they are trimmed regularly. The campground is quiet, clean, comfortable, and pet friendly. They have an awesome staff and managers. Its a newer park for the area with spacious sites. Our Verizon service worked well and at times, their free wi-fi worked better than our My-fi Internet card. They even have mail service.
The campground is privately owed and well maintained they have some of the cleanest restroom/showers weve ever seen! Its a great area with many things to do. We kayaked one day and played golf the next, in month of December. We are definitely returning!
