Dumping Without a Hookup: How to Use an RV Tote Tank

Guide · Updated 2026-11-09 · General guidance; rules vary by state, park, and operator, so follow posted signs.

Short version: a portable tote tank lets you empty RV tanks without moving the RV. Fill it from your outlet with a short hose, cap it, move it slowly (by hand, or towing at walking pace if the manufacturer allows it), and empty it at an approved dump station or sewer inlet. Check campground rules first, and never empty it anywhere else.

If you camp for more than a few days at a site without a sewer connection, your tanks will eventually fill before you’re ready to pack up. Breaking camp, driving to the dump station, and setting up again is a lot of work for a half-full gray tank. A portable waste tote, often called a “blue boy” after an early brand, solves that. It isn’t glamorous, but done right it’s clean and simple.

When a tote makes sense

When it doesn’t make sense: when the dump station is a long way away on public roads, when the campground prohibits totes, or when you can’t safely control a full one on the terrain.

Choosing a tote: size, wheels, and fittings

Totes come in a range of capacities. Bigger means fewer trips but much more weight. Wastewater weighs about as much as water, so a full tote is heavy. The right size is the one you can safely control, uphill and downhill, on the ground where you camp.

Look for:

As one example, the Camco Rhino 21-gallon tote tank on our gear page has two large wheels, a tow adapter, a built-in rinser, and a short sewer hose with a clear elbow and 4-in-1 adapter. Capacities and features vary across models. Compare them against your tank sizes and campsite.

Filling the tote

  1. Put on gloves. Set the tote on level ground near the outlet, slightly lower than the outlet if possible.
  2. Connect a short sewer hose from the RV outlet to the tote inlet. Short is better, because it drains completely.
  3. Open the vent on the tote if it has one.
  4. Open the RV valve partly or in short bursts and watch the tote’s level indicator. You can always add more. You can’t take it back.
  5. Stop before the tote is full. Leave room so it doesn’t slosh out of the vent in transit.
  6. Close the RV valve, lift the hose to drain it into the tote, disconnect, and cap the tote, inlet and vent both.

If you’re emptying both tanks, the usual order still applies: black first, gray second. If both won’t fit in one load, do black, make a trip, then gray.

Hauling it safely

This is where most tote problems happen. A full tote is heavy, top-heavy on slopes, and unforgiving.

Emptying at the dump station

  1. Position the tote next to the inlet and set it so it can’t roll.
  2. Connect the tote’s outlet hose and secure the elbow in the inlet.
  3. Open the vent, then the outlet, and lift the handle end of the tote so it drains completely.
  4. Rinse the tote with the built-in rinser, or through the inlet, using a non-potable rinse hose. Drain it again.
  5. Cap everything, rinse the pad, and close the inlet.

All the normal dump station etiquette applies, plus one more point: tote trips can take longer, so if someone’s waiting, let them go ahead between your loads.

Rules and legality

Rules about totes vary by campground, park system, and local authority. Some campgrounds welcome them, some limit where you can take them, and some don’t allow them at all. Before you buy one for a specific stay, ask the host or check the campground rules.

What’s true everywhere: empty totes only into an approved dump station or sewer inlet that allows it. Never on the ground, in a pit toilet unless it’s posted as allowed, in a storm drain, or in a ditch. That includes gray water, unless the local land manager has clearly said otherwise for that place. See the gray-water note in black vs. gray tank.

FAQ

What is an RV tote tank?

A portable waste tank on wheels. You fill it from your RV's sewer outlet with a short hose, then roll or slowly tow it to a dump station or sewer inlet to empty it, so you don't have to move the RV.

What size tote tank should I get?

Bigger totes mean fewer trips but are much heavier when full, since wastewater weighs about as much as water. Pick a size you can safely control when full, on the terrain you camp on.

Can I tow a tote tank behind my truck?

Many totes include a tow adapter, but they are designed for very slow towing. Follow the manufacturer's speed limit, keep to campground roads where it is allowed, and never tow on public roads at traffic speed.

Where can I empty a tote tank?

At a dump station or sewer inlet that allows it. Some campgrounds have rules about totes, so ask the host or check the posted rules. Never empty a tote on the ground or into a storm drain.

Can I use a tote for black water?

Yes, most totes are designed for both gray and black water. Many people prefer to do the black tank in one trip and gray in another, and to rinse the tote afterward.
