We stayed at the Trailer Village at the South Rim this past weekend. It was cold, but manageable. The village has full hookup, including cable. WIFI is not available at the RV site, but is available at a nearby location. A shuttle bus pick up is located at the village and it transports you to all the points of interest on the South Rim, visitor center, and general store (which is within walking distance from the RV site). We really enjoyed the RV site.
