Full Hookup vs Partial: Which RV Site You Actually Need

Aug 6, 2026

"Full hookup" gets treated like the safe default, the box you check so you don't have to think. It isn't the safe default. It's the expensive default, and a lot of the time you're paying twenty extra dollars a night for a sewer pipe you'll never touch. I've done both, on the same trip, and the difference that matters is almost never the one people assume.

The honest version: most people don't know what they're actually buying when they pick a site type. They see "full" and think "better." Sometimes it is. Sometimes it's the reason a weekend cost forty percent more and the spot was ten feet from the highway instead of by the creek. This is the part the booking page doesn't tell you.

What the terms actually mean

Three levels show up, and the words get used loosely:

Electric only. A pedestal with power. You arrive with fresh water in your tank and you leave by dumping your tanks on the way out. That's the whole deal. You are fully self-contained, the park just lends you an outlet.

Partial (water and electric). Power plus a water spigot right at your site, so you can top off the fresh tank without hauling jugs. Still no sewer. This is the most common "real" site at state parks, and honestly the one most weekend trips actually need.

Full hookup. Power, water, and a sewer connection at the site. You can empty your gray and black tanks whenever you want, run the shower like a hotel, and never think about a dump station. For the right trip, that calm is worth real money.

Notice what's missing from those definitions: amp service, water pressure, site location. "Full hookup" tells you nothing about whether you'll be on 30 or 50 amp, or whether the spigot sputters. Those details sit in the fine print, and they matter more than the hookup label most days.

What the pedestal is really selling you

The power is the part you can't fake. If a site has no electric, you're on battery and generator, and that's a different kind of trip. So "electric only" versus "partial" is a small jump: you gain a water spigot. Nice, but not life-changing.

The big jump is partial to full, because that's the sewer line. And the sewer line only matters if your tanks would otherwise fill up during your stay. That's the whole economic question, and it comes down to one thing: how long are you staying, and how many people are showering.

How long your tanks actually last

This is the number nobody does the math on. A typical travel trailer or Class C carries roughly 30 to 50 gallons of fresh water, 30 to 40 of gray (sinks and shower), and 30 to 40 of black (toilet). Smaller rigs are less; big fifth-wheels more. But the ratios hold.

Gray fills fast. Two people, normal cooking and a couple of quick showers, and you're looking at maybe three to four days before the gray tank is full. Black fills slower, because you're not exactly using the toilet constantly, but a family of four with kids who drink a lot of juice and then need the bathroom at 11 p.m. can fill a black tank in two or three days.

Here's the thing most first-timers miss: you don't dump the black tank when it's at 25 percent. You wait until it's nearly full, because you need volume and a good downward rush to actually clean the sensors and the tank walls. Dumping a barely-used black tank is how you end up with a sensor that lies to you forever. So even "full hookup" doesn't mean "empty daily." It means "empty when it's actually full, without driving anywhere."

If your stay is two nights, your tanks aren't filling. You will leave with room to spare. Paying for a sewer connection you'll use once, on the way out, at a dump station you were already going to pass, is the classic overpay.

When partial is completely fine

Short trips. One night, two nights, even three if nobody's treating the shower like a spa. I've done weekenders on electric-only and never felt deprived, because the math above means my tanks had plenty of headroom.

State parks love the simpler sites, and they're usually the better spots: tucked into the trees, closer to the trail or the lake, quieter than the full-hookup row that always seems to sit in the open sun by the road. You pay less and you camp better. The trade is you carry your water and you dump on exit, which is a five-minute errand you were going to run anyway.

If you're the kind of camper who likes to boondock, partial sites are good training. They teach you to use less: shorter showers, catch-the-dishwater discipline, the habit of not letting the faucet run. That skill pays off later at real dispersed sites where there's no spigot at all.

When full hookup earns its price

Now the other side, because it's real.

Staying a week or more. That's the line. Past day three or four, tanks start biting, and the ability to just open a valve instead of planning a dump run changes the trip from "managing waste" to "not thinking about it." For a long stay, full hookup isn't a luxury, it's the thing that keeps the trip from developing a low-grade dread.

Traveling with kids. Little ones shower twice a day, spill things, need the bathroom constantly. Your gray tank will fill whether you like it or not, and a cranky toddler plus a full black tank is a combination you do not want to meet on day five. Full hookup turns "we need to find a dump station" into "I opened a valve."

First-timers. Your first RV trip should not include a dump-station lesson. There's enough to learn: backing in, leveling, the water pressure regulator you forgot, where the gray and black actually connect. Removing "figure out the sewer" from that list is worth real money for a lot of people, and nobody should be ashamed of buying that calm.

Working from the rig. If you're parked for a stretch and living in it, full hookup is basically mandatory. You're generating normal-household amounts of gray water, doing laundry, running the AC on 50 amp. Partial will work, but you'll be watching tank levels like a hawk. Not the headspace you want on a work call.

Anyone running a washer or using the shower as their main one. That's just volume math again. If your gray tank would fill mid-stay, the sewer line pays for itself.

Run the numbers before you assume partial is cheaper. Our trip budget calculator lets you plug in nights and site type and see the real delta, and sometimes the "expensive" full hookup is only a few bucks a night once you account for the dump-station detour you'd otherwise make.

The sewer connection itself, demystified

People fear the sewer line more than they fear the road. It's not that bad, and the fear is the reason a lot of people overpay for full hookup "just in case."

You screw a hose (the "stinky slinky," a name that's funnier than the object) from your rig's black-valve outlet to the campground's inlet. You open the black valve, let it rush, close it, open the gray to flush the hose with soapy water, done. The first time is awkward. The third time is a non-event. The "gross factor" wears off faster than the cost of a week of full-hookup sites.

Etiquette matters and it's simple: don't leave the hose connected and open (tank needs to stay sealed to build pressure for a clean dump), don't cross-connect, and for the love of everyone, secure the cap. That's the whole list.

The amp service gotcha nobody mentions

Here's a real trap. A "full hookup" at a premium site might be 50 amp; a partial might be 30. If your rig is 50 amp and you book a 30-amp partial because it was cheaper, you either run a dogbone adapter and throttle your power, or you can't run the AC and the microwave at once. In August. In Texas.

So when you compare site types, check the amp, not just the hookup label. A 30-amp full hookup and a 50-amp partial are not the same camping experience, and the booking filter that just says "partial" is hiding that detail. Match the amp to your rig first, then worry about the sewer.

Water pressure, the quiet killer of hoses

Hookup sites deliver park water, and park water pressure is all over the map. Some spigots will blow out your hose and your regulator if you don't have a pressure regulator screwed on first. This applies to partial and full equally, but it's worth saying here because new folks buying a "nicer" full-hookup site assume the plumbing is gentler. It isn't. Screw a regulator on before you connect, every time, or you'll be buying a new hose at the camp store for triple price.

While we're at it: a short potable-water hose, distinct from your sewage hose, and never the two touching. The color-coding exists for a reason.

Dump stations, and why "partial is fine" usually holds

Even on electric-only and partial sites, nearly every park has a dump station you roll through on the way out. It's a concrete pad with a big inlet, you do the same hose routine you'd do at a full site, and you drive off. Five minutes, once, at the end. The scary part is the anticipation, not the act.

So the "no sewer" downside is really "one short stop at the end of the trip." If your stay is short enough that tanks don't fill, that's a non-issue. Don't let the absence of a sewer pipe talk you into a more expensive site by default.

The mistakes that actually cost people

Overpaying on a two-night trip. You booked full hookup because it sounded safer, then realized the partial site next door was shaded, cheaper, and ten steps from the lake. Match the site to the stay. Short trip, decent weather, dump station on exit? Partial is fine.

Booking full for "peace of mind" on a solo trip. One person, three days, you'll use maybe a third of your fresh tank. The sewer line sat unused. That's the most common waste I see, and it's pure habit, not need.

Ignoring amp and getting cooked. Covered above, but it belongs in the mistake list because it happens constantly. A 30-amp site in a heat wave with two adults running AC is a fight you lose.

Burning through water because the spigot is right there. Partial and full both tempt you to treat water like a house. You can't. Fresh tank is finite and refilling means packing up or finding a fill station. Shorter showers still apply, even with a spigot at the site.

Assuming "full" means "better located." It often means the opposite. Full-hookup loops get placed where utilities were easy to run, which is frequently the open, sunny, road-adjacent part of the park. The pretty shaded sites are usually partial. You can trade a sewer line for a view without meaning to.

A simple way to decide

Forget the label. Answer four questions:

How many nights? One to three, partial or even electric-only is plenty. Four-plus, lean full.

How many people, and how young? Solo or a couple, you'll barely dent tanks. A family with kids showering constantly, go full and stop calculating.

First trip? If yes, buy the calm. Full hookup removes the one task newbies fear most.

Working or parked long? Full, no debate.

That's it. Length, headcount, experience, and whether you're living in it. The hookup label is the answer those questions produce, not the other way around.

Using the filter instead of guessing

Our directory lets you filter by amenities, so you don't book blind and discover the "full hookup" was 30 amp after you've driven six hours. Pick your city, tick full hookup, and see what's actually there, amp and all.

The honest version

Full hookup is not the best site. It's the site for a specific trip: long stay, lots of people, first timer, or living in the rig. Everything else, partial or even electric-only will do the job and often put you in a better spot for less money. The booking world pushes "full" because it's the premium tier and premium tiers sell. Your job is to notice when you're paying for a sewer pipe you won't use, and to grab it without flinching when your tanks would otherwise rule your week. Match the site to the stay. That's the whole guide, and the rest is just hose management.
