RV Park Hookups Explained: 30-Amp, 50-Amp, Full Hookups, and Which Rig Needs What (2026)

Before you book your next site, make sure the hookups actually match your rig. Getting this wrong means running on generator, rationing your AC, or worse — damaging your electrical system. Here's everything you need to know.

The three hookup levels at a glance

Most RV parks offer some combination of electric-only, water/electric, and full hookups. Here's what each means:

• Electric only — Power pedestal, no water or sewer connection at the site. You'll need to dump at the park's dump station.
• Water/electric (W/E) — Power and fresh water at your site. No sewer; plan for dump station use every few days.
• Full hookups (W/E/S) — Power, fresh water, and sewer. Most preferred by full-timers and long-stay RVers — no dump runs needed.

30-amp vs 50-amp: what's the real difference?

This is the question we get most often — and the answer matters more than most RVers realize.

30-amp service

A 30-amp, 120-volt hookup delivers about 3,600 watts of power. That's enough for one roof AC unit, your refrigerator, and basic appliances — but not much more running simultaneously. If you have a smaller rig (under 32 feet), a single AC unit, and you're not running the microwave and AC at the same time, 30-amp is fine.

Most travel trailers, 5th wheels under 30 feet, and all Class B campervans are wired for 30-amp. Plugging a 30-amp rig into a 50-amp pedestal is safe with an adapter — you'll just only draw 30 amps.

50-amp service

A 50-amp, 240-volt service delivers up to 12,000 watts — roughly three times the power. If your rig has two roof AC units, an electric water heater, or a washer/dryer, you likely need 50-amp. Larger Class A motorhomes, high-end 5th wheels, and most toy haulers are wired for 50-amp.

Plugging a 50-amp rig into a 30-amp pedestal is possible with a dogbone adapter, but you'll need to manage your power carefully — no running both ACs simultaneously.

Full hookups: the full-timer's must-have

If you're staying longer than a week, full hookups become almost essential. Driving to a dump station every 3–4 days is fine for weekend trips but adds real friction to long stays. Parks that advertise full hookups with 50-amp and reliable sewer connections are consistently the highest-rated on RVSpot.

What to verify before booking:

• Sewer connection type — Is it a 4-inch cleanout or a 3-inch? Most rigs fit both, but confirm.
• Is sewer at every site or just some? — Many parks offer full hookups only on premium sites; standard sites may be W/E only.
• Water pressure — Quality parks offer 45–65 PSI. Use a water pressure regulator regardless.

Other amenities that actually matter

Wi-Fi quality

Most parks advertise Wi-Fi. Very few deliver it well. On RVSpot, look for parks that list a Wi-Fi speed tier — anything above 25 Mbps download is usable for remote work; 50+ Mbps is excellent. Call the park directly and ask for a speed test result before committing to a stay.

Site length and pull-through availability

Class A and large 5th wheel owners: always check maximum site length before booking. A 40-foot rig won't fit in a 35-foot back-in site. Pull-through sites eliminate the reverse-parking challenge and are worth paying a premium for on long stays.

Laundry, mail, and package acceptance

For long-term stays, on-site laundry saves significant time. Mail forwarding service and package acceptance (especially for Amazon delivery) are increasingly important for full-timers — and some parks don't offer it at all. Worth a quick phone call before committing to a monthly rate.

How to use RVSpot filters to find the right hookup

RVSpot's search page lets you filter by hookup type. Look for the full hookups option to find parks with water, electric, and sewer at the site.
