RV Slang: Common RV Phrases and Terms New RVers Should Know

RV culture has a language of its own. Spend enough time at a campground or around experienced RVers, and you’ll start hearing terms like “boondocking,” “shore power,” “toad,” and “dry camping” tossed around like everyone knows exactly what they mean.

If you’re new to RVing, some of that lingo can be confusing at first, but a few terms are actually pretty important to understand before you hit the road. Below, we’ll break down some of the most common RV slang, abbreviations, and phrases you’re likely to hear so you can follow the conversation and better understand how your RV works.

And because RV batteries and electrical systems come with plenty of terminology of their own, we’ll also cover some of the electrical and battery terms that matter when you’re using, maintaining, or upgrading your RV.

Campground and Campsite Lingo

One of the first places you’ll start seeing unfamiliar RV terms is when you’re booking a campsite. Campground listings and reservation pages use all kinds of shorthand for site types, hookups, and even different kinds of RVs.

Most of it makes sense once you know what it means, but it can be confusing the first few times you run into it.

Here are some of the most common campground terms you’re most likely to come across:

• Rig: A general term for an RV. Motorhomes, travel trailers, fifth wheels, truck campers, and other RVs can all be called rigs.
• Coach: Another term for a motorhome, especially a larger Class A motorhome.
• Fiver: Short for fifth wheel, a towable RV that connects to a hitch in the bed of a pickup truck.
• TT: A common abbreviation for travel trailer.
• Hookups: The utility connections available at your campsite. Depending on the site, these may include electric and water hookups before sewer is added.
• Full hookups: A campsite with electric, water, and sewer connections. In other words, full hookups include water hookups along with electric and sewer. You may also see this shortened to FHU on campground listings and reservation sites.
• Partial hookups: A campsite that gives you some utilities but not all of them. Electric and water without sewer is a common setup.
• Shore power: Electricity your RV gets by plugging into an outside power source, usually a campground pedestal. Most RVs use either a 30-amp or 50-amp connection. 
• Pull-through site: A campsite you can drive straight into and out of without having to back your RV into the space.
• Back-in site: A campsite where you have to back your RV into position.
• Buddy sites: Two campsites set up next to each other so friends or family can camp beside one another.
• Camp host: Someone who stays at the campground and helps with day-to-day tasks, answers questions, and assists guests when needed.

Next, let’s look at the terms that come up when you’re camping without the usual campground utilities.

Boondocking, Dry Camping, and Camping Without Hookups

Camping without hookups is a big part of RV life for a lot of people, whether you’re spending a night somewhere on the way to your next stop or heading far away from a traditional campground. When you’re relying on your own water, batteries, fuel, and supplies, a few terms start coming up again and again.

Here are some of the most common ones:

• Boondocking: Camping without water, sewer, or electric hookups. This often means camping outside a traditional campground and relying on what you have onboard.
• Dry camping: Camping without hookups. It’s often used in much the same way as boondocking, although you can also dry camp inside a developed campground that simply doesn’t offer hookups.
• Dispersed camping: Camping outside a developed campground, usually on public land with few or no services.
• Off-grid: Camping without relying on campground utilities. Your batteries, water tanks, solar setup, generator, and other onboard systems have to provide what you need while you’re there.
• Moochdocking: Staying in your RV on someone else’s property with permission, such as a friend’s driveway or a family member’s land.
• Wallydocking: Spending the night in a Walmart parking lot while traveling. Not every store allows overnight RV parking, so always check before staying.
• Dump station: A designated place where you can empty your RV’s gray and black tanks when you don’t have a sewer connection at your campsite.

The longer you spend around RVers, the more you’ll notice that the lingo isn’t only about campsites and equipment. There are also plenty of terms for the different ways people travel and live in their RVs.

RV Lifestyle, Full Timers, and Community Lingo

Some people RV a few weekends a year. Others spend months on the road or live in their RV full-time. Not surprisingly, there are plenty of terms for the different ways people travel and live in an RV.

You’ll hear these pretty often around campgrounds and other RVers:

• Full timer: Someone who lives in an RV full-time as their main home.
• Part timer: Someone who RVs for part of the year or takes regular RV trips but still has a permanent home.
• Sticks and bricks: RV slang for a traditional house. Full timers may use it when talking about a home they still own or life outside the RV.
• Snowbird: An RVer who heads somewhere warmer for the winter, often traveling south and returning north once the weather warms up.
• Workamping: Working while traveling in an RV. Workampers often take seasonal jobs at campgrounds, parks, resorts, and similar places in exchange for pay, a campsite, or both.

Then there’s the more technical side of RVing. Once you start talking about batteries, charging, converters, inverters, and electrical systems, there’s a whole different set of terms to know.

RV Electrical and Battery Lingo

You don’t need to be an electrician to enjoy RVing, but knowing a few basic electrical and battery terms can make it much easier to understand your setup, troubleshoot problems, and figure out what you actually need when it is time to upgrade.

Here are some of the terms you’ll hear most often:

• House battery: The battery that runs many of your RV’s 12 volt systems, including lights, the water pump, fans, controls, and other equipment.
• Chassis battery: The starting battery used to start the engine in a motorhome. It is separate from the house battery that runs the living area.
• Slide-out: An extension on some RVs that moves outward when parked to expand the living space.
• Basement: The storage area under the main living space of an RV, often used for gear, tools, and supplies.
• Battery bank: One or more batteries connected together to supply electricity to your RV.
• 12-volt side: The part of your RV’s electrical system that runs on DC electricity from the house batteries.
• 120-volt side: The AC side of the system used by standard household-style outlets and appliances. Electricity may come from shore power, a generator, or an inverter.
• Converter: A device that changes 120 volt AC electricity into 12 volt DC electricity. It also helps charge the house batteries when the RV is connected to shore power or a generator.
• Inverter: A device that changes DC electricity from your batteries into AC electricity so you can run certain outlets and appliances when you are not plugged in.
• Inverter charger: A unit that combines an inverter and battery charger in one piece of equipment.
• Amp draw: The amount of electrical current a device is using at a given time.
• Amp hours: A measurement of battery capacity. If you see a battery listed as 100Ah, the Ah stands for amp hours.
• State of charge: Usually shortened to SOC, this tells you how much charge is left in your battery, usually as a percentage.
• Parasitic draw: Small amounts of electricity used by equipment that continues drawing from the battery even when you think everything is turned off.
• BMS: Short for Battery Management System. In lithium batteries, the BMS helps protect the battery by monitoring things like voltage, temperature, charging, and discharging.
• LiFePO4: Short for lithium iron phosphate, a lithium battery chemistry known for its long lifespan, stable performance, and lighter weight compared with traditional lead-acid batteries. It’s the chemistry used in Ionic lithium batteries from LithiumHub.

A Few More Battery and Charging Terms

Lithium batteries, solar setups, and larger RV electrical systems come with a few extra terms that are helpful to know.

• Depth of discharge: The percentage of a battery’s capacity that has been used.
• Cycle life: The number of charge and discharge cycles a battery can go through before its capacity drops significantly.
• Drop-in replacement: A battery designed to replace a similar-size lead-acid battery without major changes to the battery compartment. You still need to make sure the rest of the charging system works with lithium.
• Series wiring: Connecting batteries so their voltages add together. For example, two 12-volt batteries wired in series create a 24-volt system.
• Parallel wiring: Connecting batteries so voltage stays the same while available amp-hour capacity increases. If you want a closer look at how the two setups work, we have a full guide to series vs. parallel battery connections.
• Solar array: The group of solar panels used to charge an RV battery system.
• Charge controller: The device that manages electricity moving from solar panels into the batteries.
• MPPT: Short for Maximum Power Point Tracking, a type of solar charge controller designed to get more usable electricity from the solar panels.
• Genset: Short for generator set. It simply means a generator, either portable or built into the RV.

Knowing these terms makes it much easier to understand how your RV’s battery and charging systems work together.

Towing and Driving Lingo

If you tow a travel trailer or fifth wheel, drive a larger RV, or pull a vehicle behind a motorhome, you’ll run into a whole different set of terms. Some are just common RV slang, while others are useful to know because they deal with towing, weight, and safety.

• Tow rig: The vehicle used to pull a travel trailer or fifth wheel.
• Tow rating: The maximum weight your vehicle is rated to tow.
• Tongue weight: The amount of weight the trailer puts down on the hitch.
• Sway: Side-to-side movement of a trailer while towing.
• Chucking: Rough back-and-forth or up-and-down movement you may feel while towing a fifth wheel or trailer.
• Porpoising: An up-and-down rocking motion between the tow vehicle and trailer.
• Toad: A vehicle being towed behind a motorhome.
• Dinghy: Another name for a vehicle towed behind a motorhome.
• Hula skirt: A flap or guard behind the rear tires that helps protect a towed vehicle from rocks and road debris.
• Flat towing: Towing a vehicle with all four wheels on the ground.
• GVWR: Gross Vehicle Weight Rating, or the most your fully loaded vehicle is allowed to weigh.
• GAWR: Gross Axle Weight Rating, or the most weight that can be placed on a single axle.
• GCWR: Gross Combined Weight Rating, or the maximum total weight of your tow vehicle and trailer when everything is loaded up.

The weight abbreviations may not be the most interesting RV terms, but they’re worth knowing before you start towing.

Water, Waste, and Tank Talk

Every RVer eventually learns this vocabulary. Once you know the difference between the fresh, gray, and black tanks, and how the holding tanks work as the onboard waste-storage system, the rest starts making a lot more sense. 

• Fresh water tank: The onboard tank that stores clean water for things like cooking, washing, and showering.
• Gray water: Wastewater from sinks and showers.
• Gray tank: The tank that holds gray water until you can empty it.
• Black water: Wastewater and sewage from the RV toilet.
• Black tank: The tank that stores toilet waste.
• Stinky slinky: RV slang for the flexible sewer hose used to empty the gray and black tanks.
• Blue boy: A portable tank used to move wastewater to a dump station.
• Dump station: A designated place where RVers can empty their waste tanks.
• Honey wagon: A service vehicle that pumps out sewage from RVs.
• Backflushing: Sending water back through the black tank system to help loosen and remove buildup.
• Tank rinse: Using a built-in connection or rinse system to spray water inside the black tank after dumping.
• Potable water: Water that is safe to drink.
• Nonpotable water: Water that is not safe for drinking and may be available at dump stations for rinsing tanks or equipment.
• Navy shower: A water-saving shower where you get wet, shut the water off while washing, and turn it back on to rinse.

Once you know these terms, it’s a lot easier to understand campground hookups, dump stations, and what’s happening with your RV’s water and waste systems.

More RV Slang Terms You Might Hear

Not every RV term fits neatly into hookups, towing, or tanks. Some are simply part of RV culture and tend to pop up once you spend more time around other travelers. 

Here are a few more terms you’re likely to hear along the way:

• Maiden voyage: The first trip taken in a new RV.
• Winnebago: A well-known motorhome brand often nicknamed Winnie.
• Shake down trip: A short first trip used to test the RV, learn how everything works, and find any problems before taking a longer trip.
• Leveling: Getting the RV reasonably level after parking.
• Chasing 70 degrees: Traveling from place to place to stay where the weather is comfortable.
• Caravanning: Traveling with other RVers and following roughly the same route or schedule.
• Home base: The place you consider “home” between RV trips or return to when you’re not traveling.

You probably won’t use every bit of RV slang you hear, but knowing what people mean makes campground conversations, RV forums, videos, and even owner manuals a lot easier to follow.

Once You Know the Lingo, RV Life Gets a Lot Easier

You don’t need to memorize every term before your first RV trip. Most of them start to stick naturally once you’ve booked a few campsites, hooked everything up, emptied the tanks, and spent some time around other RVers.

Still, knowing the basics ahead of time helps. Campground listings make more sense, conversations are easier to follow, and it’s easier to ask the right questions when you’re trying to figure something out.

And when you hear a term you don’t recognize, chances are you’re not the only one. RVers have come up with plenty of slang over the years, and there’s always something new to learn along the way.
