In the U.S., campsites are clearly categorized by the type of hookups:
- Full hookup: Includes all three connections—electricity, water, and sewer. You can connect your RV directly to the water supply and keep faucets open; water flows straight into the system, bypassing the tank, and wastewater goes directly into the sewer. Your RV functions like a regular home, with no need to manage tank levels.
- Partial hookup: Typically includes electricity and water only. You’ll need to use a dump station periodically.
- No hookups / Dry camping: No utilities—just a parking spot.
Electrical connections come in two types:
- 30 amp: Standard for smaller and mid-size RVs (Class C, small trailers).
- 50 amp: Higher-capacity connection for large RVs (Class A, large trailers).
These are two different outlet types. Most campgrounds offer both. Rental companies usually provide adapters (e.g., 50 to 30 amp), so connection is rarely an issue.
