Dealing with RV waste isn’t glamorous, but it’s essential. If you haven’t learned how to empty your RV’s holding tanks, start there. But if you’re comfortable with how RV waste systems work, you may want to know what an RV tote tank is and why you might need one. 

What is an RV Tote Tank?

An RV tote tank is a portable waste tank. It allows you to empty the contents of your RV’s holding tanks to the nearest dump station without transporting your entire RV. It’s a popular option for full-time RVers who aren’t always at campgrounds with full hookups, especially campers that tow travel trailers and fifth wheels

RV tote tanks come in varying sizes, but most are smaller than your RV holding tanks. That means you may need to make multiple trips to completely empty your tanks. Tote tanks are useful for extending your trip a few more days before it’s time to move your recreational vehicle. 

What are the Pros and Cons of RV Tote Tanks?

There are definite benefits to the ability to dispose of your black and grey water without moving your RV, but there are also some considerations. Let’s look at them closely:

Advantages of RV Tote Tanks

  • Tote tanks expand your campground options to parks without full hookups.
  • Tote tanks save you money by providing the option to boondock or camp at sites with fewer amenities.
  • Tote tanks help dispose of holding tank waste without hitching up and moving your RV.
  • Tote tanks can extend your stays when camping off-grid.

Disadvantages of an RV Portable Waste Tank

  • Tote tanks need storage space when it’s not in use
  • Tote tanks may need multiple trips to the dump site because the capacity is less than your RV’s holding tanks.

Why You Might Need an RV Tote Tank?

RV tote tanks are great for many reasons. First off, always finding RV parks with full hookups isn’t a reality of RV life for everyone. If you’re a weekend warrior, you probably don’t need an RV tote tank because you’re either camping at full hookup sites or staying for such a short amount of time that hitting a dump station on the way home isn’t too much trouble. 

But campers on long road trips or living on the road full-time often find themselves boondocking or staying in sites with partial hookups. The major downside of RV camping without full hookups is having to move every few days to empty your tanks. 

A portable RV tote tank removes this issue and allows you to partially empty your tanks into a tote, roll it to the dump station, empty it, and be good to go for a few more days…without moving your RV. 

So, if you’re a full-timer or you enjoy extended stays in state parks or campgrounds that typically don’t have full hookups, an RV tote tank is a great addition. They’re also good for full-timers, as you’ll have more flexibility of places to arrange monthly stays without needing a waste hookup. 

How To Use a Portable Waste Tank for your RV

Start by consulting your tank’s manual for the manufacturer’s recommendations for safe use. 

Using an RV tote tank is similar to the regular process of emptying your gray and black water tanks. The tote serves as a temporary holding tank for transporting waste from your campground to the dump station without having to move your RV. 

Before we outline the dump process, here’s what you’ll need: 

It’s also helpful to know that tote tanks have two round three-inch openings and a small waste tank vent. The opening on top is for filling the tank and the opening on the side is for dumping the tank. The vent is required to release pressure.

Emptying a Portable RV Waste Tank Step-by-Step

Now that you’re familiar with those elements, here’s how to use your portable tote tank: 

  1. Connect a 90-degree clear elbow to the fill opening on top of the tank. A clear elbow is recommended for visual monitoring when the tote is full.
  2. Attach the sewer hose between your RV’s dump outlet and the clear elbow and open the waste tank vent.
  3. Empty holding tanks into your tote the same way you’d empty them at a dump station. Black tank first, then the gray water tank. Keep in mind your tote usually has less room than your RV’s tank capacity.
  4. Close the tote tank’s vent.
  5. Detach the sewer hose from your RV’s dump outlet and connect it to the dump opening on the side of your tote. Leave the clear elbow and other end of the hose connected to the fill opening.
  6. Transport your tote to the dump station. Most totes attach to your truck hitch and can be towed at slow speeds (a recommended max of five miles per hour).
  7. At the dump station, position your tote near the dump inlet.
  8. Detach the sewer hose and 90-degree connector from the fill opening and replace the fill opening cap.
  9. Screw or set the connector into the dump inlet and then open the waste tank vent.
  10. Pull the handle on the dump opening to empty its contents. As the level drops, you may need to tilt your tank to empty completely.

How to Clean an RV Tote Tank

If you want to rinse your tote tank after you dump your RV, do it while your sewer hose is still connected. Keep the handle on your tank’s dump opening open and then follow these quick steps: 

  • Remove the tank vent cap
  • Attach a female-to-female hose adapter to your tank’s vent 
  • Connect the dump station’s rinse water hose to the hose adapter
  • Turn on the fresh water to let it flow through your tank
  • Rock the tank gently back and forth

When you see clear water flowing through your clear 90-degree connector, shut the water off, disconnect the rinse hose and hose adapter, and replace the tank vent cap. Tilt your tank to remove any remaining water. The tank should be completely empty before closing the gate valve on the dump opening and removing your sewer hose.

How To Transport an RV Tote Tank

When it’s emptied and cleaned, you’ll need to secure your tank before heading to your next destination. Some RVers simply place their portable waste tank in an underneath storage compartment or in the bed of their tow vehicle. But if you’re like me and you don’t love the idea of storing yours alongside other camping equipment, there are other solutions.

If your RV has a fixed ladder, you can install this Thetford Tote Mount system to carry your tote tank. It comes with a strap and can hold up to 50 pounds. When you’re not traveling somewhere that you’ll need your portable waste tank, you can also use it to haul bikes, camping chairs, and other gear.

You can also explore DIY solutions like strapping your tote to your trailer’s rear bumper or spare tire. Just be sure to test its security before driving to avoid a messy (and potentially costly) accident.
