RVs do not need to be plugged in but they can be. In fact, an RV can be plugged into many different sources and a plugged-in RV offers a lot of additional functionality. So most RVers prefer to be plugged into the electrical grid and a water hose when possible.

What kind of hookup does an RV need?

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.
