Best 8 RV Portable Waste Tanks

1. The Barker 30844

One of the waste tanks you should consider for your RV is the Barker 30844. The Barker 30844 has been around for some time, since this portable waste tank has been on the market since 2007. However, there have been several versions of this waste tank over the years! Since it keeps on improving, the Barker 30844 should be a consideration.

There are several benefits associated with the Barker 30844. One of its benefits is the presence of the rubber wheels, making it easier to tow by hand. The waste tank is also less noisy and more durable than previous versions of the same brand.

Please note that the Barker 30844 had previous versions, so make sure you have the latest edition for your RV since there were some issues with the previous versions. Also, please take note that the Barker 30844 has a float indicator and not an auto-stop fill shutoff, which could be less desirable for some RV owners.

2. The Tote-N-Store 25609

With an amazing capacity of 32 gallons, it is no wonder the Tote-N-Store is currently listed as one of the top sellers in its category. Of course, there are other benefits associated with this RV waste tank, making it the perfect portable choice for you.

The Tote-N-Store 25609 is a bestseller in the U.S. The most popular is the 32-gallon capacity, but there are smaller versions available of 15 gallons and 25 gallons respectively.

One of the useful extra features associated with the Tote-N-Store is the additional storage compartment; this compartment is used for the portable waste tank accessories and the rubber wheels.

Of course, there is a downside to the Tote-N-Store 25609, despite its amazing capacity and useful storage compartment. Many users find that there is a clear lack of accessories for waste dumping. Some RV owners also claim it is difficult to empty the portable tank due to its weight. However, we do want to mention the weight is directly connected to the capacity. Therefore, the lighter tanks will not be as heavy as the 32 gallons one.

3. The Tote-N-Store 20123

If the heaviness of the previous Tote-N-Store is a problem for you, then you could consider one of the more recent versions of this brand, the Tote-N-Store 20123. The Tote-N-Store 20123 is characterized by four wheels and a unique tow bracket, which makes handling the waste tank a lot easier. This version of the Tote-N-Store is also suitable for both black and grey water.

One of the biggest advantages of the Tote-N-Store 20123 is the fact that users do not have to lift a full tank to empty it, a disadvantage that was associated with the previous version of this waste tank. However, some users report that the tank can be a little bulky, yet portable enough to easily pull by hand.

4. The Barker 207844

The brand name Barker often returns in this overview of the best portable RV waste tanks, since our next recommendation is the Barker 207844.

Contrary to some RV portable waste tanks, the Barker 207844 is made from the best materials. While most brands look to keep the cost down as much as possible to increase their profit margin, Barker has created this masterpiece, a preferred choice for anyone RV owner looking for the best portable RV waste tank.

There are several benefits associated with the Barker 207844. One of the benefits is the bayonet valve, which allows users to control the release with the most accuracy. The Barker 207844 also has air tires; this ensures that the waste tank is a lot easier to maneuver.

Like most portable waste tanks for RV’s, users have reported a similar problem as experienced with most larger tanks, the weight! Fortunately, with a large capacity, users do not have to empty the waste tank as often, which makes the heavy weight an afterthought.

5. The SmartTote 2

Not all portable RV waste tanks are incredibly large and heavy; this much is proven by the SmartTote 2, a waste tank designed to be the most practical option on the market today. However, there are various versions of this waste tank available, so make sure to get the right model if you do not want to buy the wrong one.

Some of the previous versions of the SmartTote had a poor reputation, which is why it is essentials for RV owners to take care when buying this brand. One model that seems to score the best is the SmartTote 2 40517, which is compact with a decent capacity and high maneuverability.

6. The Barker 31342 Tote Tank

Barker is the best brand around for portable RV waste tanks; this much is proven by another waste tank from the Barker brand in this overview, the Barker 31422 Tote Tank. Much like our previous suggestions, this portable RV waste tank comes with a lot of functionality!

The Barker 31422 Tote Tank comes with the same benefits as the previous version, which means a lot of capacity and easy maneuverability. However, there is a clear difference between both versions though, since the Barker 31422 only has two wheels instead of four.

While some people prefer the pneumatic tired wheels for their portable waste tank, the rubber wheels on this waste tank perform well. However, the wheels are replaceable, so you can replace the rubber wheels with pneumatic wheels if you wish to do so.

7. The Barker 28508

RV lovers who have a lower RV should certainly consider the Barker 28508 over other models, since this model is specifically created for lower RV’s. The design of the Barker 28508 allows the waste tank to easily fit under a low RV and even a tent camper.

The Barker 28508 has a capacity of 15 gallons and is easy to install, so even new RV owners will have little problems using this portable waste tank. However, there is one small downside to this model, since the tow handle is a little on the short side. Still, despite the shorter tow handle, the waste tank is still easy to maneuver.

8. The Thetford 40510 Portable Waste Tank

The Thetford 40510 Portable Waste Tank is undoubtedly one of the better RV portable waste tanks on the market today. Even though it is one of the most affordable portable waste tanks, it does provide some of the key benefits RV owners look for: convenience, maneuverability, and good capacity.

When you look at the Thetford 40510 Portable Waste Tank, you will notice quite the unique design. It has a patented hose handle and even an automated shut-off for when the tank is full. Therefore, waste spillages are unlikely with this waste tank model.

We must also mention that the Thetford 40510 Portable Waste Tank does not require any special setup and installation, it can be used immediately. So, anyone who is looking for an affordable but also effective waste tank should consider the Thetford 40510 Portable Waste Tank.

FAQ

Can you poop in an RV?

Haha! Yes, you can take a poop in an RV.

The toilets are slightly different than the ones we have at home, so they may get clogged more often.

Not too big of a deal to worry too much about, just make sure to follow the precautions and you’re good to go.

Unlike the toilets we use at home, the ones in an RV doesn’t have septic tanks that can flush. Instead, the waste goes through a valve that you open with a foot pedal or an equivalent lever.

Kind of like in an airplane or on a greyhound bus.

Can you flush toilet paper in RV?

Yes, you can!

Just remember to use single ply, septic tank-friendly toilet paper.

Why?

Because the type of paper is a determining factor of the condition of the tank.

Clogging the septic tank with the wrong kind of toilet tissue will not only give false readings on the tank sensor but can lead to significant septic issues as the tank fills.

How often do you need to dump RV waste?

You should dump RV waste as often as everyday or as infrequent as once a week.

This depends on how large your traveling group is. If it’s only 1-2 people, then you probably get away with dumping waste once a week. If it’s a group of 10, then probably twice a day!

How do you clear a clogged RV toilet?

Gross! Just talking about it brings back the nasty scent and memory of unclogging toilets in the RV.

A clogged toilet in your RV can happen quite often, because it’s built differently than the one in your home. It can’t handle as much damage.

You can try one of these 5 methods to unclog your RV toilet:

  1. Hot Water
    • Pour (a lot of) boiling water down the toilet, let it sit overnight then flush. This will probably smell, so beware.
  2. Chemical Cleaners
    • Not unlike what we do with our clogged toilets in a house, pouring chemicals down the drain can break down the waste.
    • Check out this article we wrote about the best RV toilet chemicals to use.
  3. RV Toilet Tank Wand
    • For heavy-duty jobs only, a toilet tank wand is a piece of machinery that snakes your drain with a high-pressure spray
  4. Ice Cube
    • I haven’t tried this but many people swear by it. Fill the toilet basin with water (⅓) and ice (⅔). Drive around as you flush the ice down the toilet. Apparently it works.
  5. RV Macerator Pump
    • Another heavy-duty machinery, this pump breaks down bigger solids into small bits, so it can smoothly go down the drain
    • Follow our DIY step-by-step guide here.

To keep your RV toilet unclogged, remember to clean and empty out the tanks regularly, and use septic-safe toilet paper.  

What’s the difference between a gray and black RV water tank?

Yes, there is a difference between the two.

A black water tank only holds the waste water from your RV toilet. Whereas, the grey water tank is where all the other used “grey water” gets stored. Typically, from your shower, restroom sink and kitchen sink

Conclusion 

Our top pick is The Barker 207844​!

Why?

For many reasons actually. 

This product has been around for a long time now (since 2007!). Typically this means that it's a good product and iterations have been made upon the original.

It only weighs 37 pounds when empty - that's pretty light. 

Easy to maneuver with the rubber wheels - making it less squeaky and longer lasting

The valves are 3 inches thick and it has zinc-plated steel for antibacterial properties.

Just note that there's a float indicator instead of an auto-stop fill shutoff. That's not good or bad, just depends on your preference.
