Most RV parks provide either partial hookups, which include electricity and water, or full hookups, which add sewer service. Some deluxe parks also include hookups for cable television and telephone lines.
Water hookups allow RV travelers to connect their rigs directly to the campgroundâs fresh-water supply. The water typically comes from the municipal water supply or a campground well and is considered potable, or safe to drink. Water hookups are provided at all but the most remote or primitive campgrounds.
