Top 5 Best RV Portable Waste Tanks
10 Best RV Portable Waste Tanks Review
1. Camco Rhino 36-Gallon Camper/RV Tote Tank
The Camco Rhino 36-Gallon Tote Tank is designed for RVers who demand maximum capacity and an all-inclusive system for black and gray water transport. It’s the ideal solution for full-time RVers and those with large rigs who frequently boondock or stay in sites without sewer hookups, offering a hefty capacity that minimizes trips to the dump station. The patented Rhino design is constructed from durable, UV-stabilized HDPE, ensuring a leak-free and long-lasting performance on the road. This comprehensive kit includes every accessory needed to get started, making it a favorite for reliability and convenience.
In terms of performance, the large, heavy-duty, no-flat wheels are a key feature, allowing for effortless towing behind a golf cart or truck using the included steel adapter, even over rough terrain. Moreover, the integrated gate valve and rinser—a critical feature for maintaining hygiene—make the final cleaning process much less messy and far more thorough than tanks without a dedicated rinsing port. However, due to its size and robust construction, be aware that while easy to tow, this tank is quite heavy when empty and can be challenging for one person to maneuver and lift when full.
Ultimately, the Camco Rhino 36-Gallon stands out for its complete accessory package and rugged build, offering excellent long-term value. For those managing a large volume of waste and prioritizing a trouble-free dumping process, this tank is hard to beat. If you are looking for a highly capable, heavy-duty tote that comes ready to use, this is a top-tier choice among the best RV portable waste tanks available.

2. Barker 4-Wheeler Tote Tank – 42 Gallon
The Barker 4-Wheeler Tote Tank is a robust, premium solution designed for maximum stability and ease of maneuverability, particularly appreciated by those with large Fifth Wheel trailers or long-term campsite setups. With a massive 42-gallon capacity, this tote significantly reduces the frequency of dumping trips, which is ideal for large families or extended stays. Its distinguishing feature is the four-wheel design, which includes front-swivel wheels, providing superior balance and smooth transport compared to two-wheeled models that require more lifting and tilting when turning.
The performance is excellent due to the heavy-duty construction and high-quality pneumatic tires, which roll quietly and absorb bumps better than solid plastic wheels, making for a smooth journey across different terrains. Moreover, the front-swivel feature is an undeniable strength, allowing the full tank to be pulled and steered with surprising ease. A minor drawback is that some users note the need for a separate vent feature for faster dumping, as relying solely on the included level gauge/valve can sometimes slow the flow. Also, the connection hose provided is noted to be quite short, often requiring an extension.
Ultimately, the Barker 4-Wheeler is the go-to choice for RVers needing the largest possible capacity and the smoothest, most stable towing experience. It is built to be a reliable workhorse for managing substantial waste volume over longer periods. For those prioritizing stability and effortless movement of a fully loaded tank, the Barker 42-Gallon is truly one of the Best RV Portable Waste Tanks, offering exceptional value and a durable build.

3. Camco Rhino 21-Gallon RV Portable Waste Tank
The Camco Rhino 21-Gallon is the mid-sized workhorse in the popular Rhino lineup, offering a perfect balance between capacity and portability. This tank is specifically tailored for weekend warriors or those with smaller RVs and travel trailers who need a reliable, compact waste management system. It shares the same durable, UV-stabilized, blow-molded HDPE construction as its larger counterpart, ensuring longevity and resistance to leaks. Furthermore, its size is ideal for fitting on an RV ladder using the integrated hook, providing simple and secure storage when not in use.
Performance is enhanced by large, no-flat wheels and a removable steel tow adapter, making the movement of a full tank effortless by either rolling it manually or towing it slowly. The low drain hole is a major strength, as it ensures the tank empties completely, minimizing residue and improving sanitation. Moreover, the built-in rinser is excellent for quick and thorough cleaning. The main drawback for some users is that the 21-gallon size may necessitate two trips for a large black tank if not planned carefully, particularly with longer stays.
Overall, the Camco Rhino 21-Gallon stands as one of the best RV portable waste tanks for couples or small families, offering the robust features of the larger Rhino tanks in a much more manageable package. It provides the full kit and reliable performance needed to manage waste efficiently without the bulk of a 36 or 42-gallon model. If portability and ease of storage are key concerns, this Rhino tank delivers excellent functionality.

4. YITAHOME 19.8 Gallon Portable Water Holding Tank
The YITAHOME 19.8 Gallon Portable Tank offers a unique design focused primarily on water hauling (freshwater or sewage) with excellent user-friendly features, making it stand out from the conventional dedicated RV tote tanks. With a 19.8-gallon capacity, it is appropriately sized for small to mid-sized RVs or for general-purpose water management at a campsite. Its appeal lies in the highly portable, integrated design that eliminates complex setup, making it immediately ready for use upon delivery. It’s particularly suited for campers who need a simple, quick way to manage gray water from an outdoor kitchen or small tent camper.
The performance benefits come from the combination of a built-in handle and large universal wheels, which provide superior, one-person maneuverability. Furthermore, the rotating pouring spout is a major advantage for quick and splash-free emptying, offering a cleaner, more comfortable experience. A useful level indicator is also included to prevent messy overflows, which is not standard on all portable waste tanks. The main issue, according to some buyers, is that the tank’s ports are not designed to accommodate standard RV sewer hoses and fittings seamlessly, which creates inconvenience and can result in odor if not secured properly.
Ultimately, the YITAHOME tank is an excellent choice for those prioritizing simple, manual movement and quick-dump features, particularly for gray water or smaller black tank volumes. If your primary need is for a dedicated, high-capacity black tank solution with universal sewer hookups, another option from the list of best RV portable waste tanks may be better. However, for general utility and ease of handling, this model is a strong contender.

5. Class A Customs 14 Gallon RV Waste Black Water Holding Tank
The Class A Customs 14-Gallon tank is fundamentally different—it is a *stationary* holding tank designed for custom installation, not a portable roll-away tote. It’s the perfect component for builders of tiny houses, custom RVs, or van conversions who need a dedicated tank for black or gray water where a standard portable option won’t suffice. Made in the USA from durable MDPE resin, this tank offers seamless, one-piece construction for a leak-free system. Its compact, rectangular dimensions make it easy to integrate into tight spaces, especially under small van life vehicles that may use a cassette toilet.
The performance of this tank relies heavily on proper installation. It comes with a pre-installed 3-inch ABS female pipe outlet but requires the end-user to determine and install the inlet and vent fittings, which allows for customization but demands plumbing knowledge. A major strength is the MDPE material, which is thick and non-corrosive, designed for waste water only. However, its main drawback is the complete lack of portability features—no wheels, no handles, and no accessories. Additionally, it requires metal bracing for mounting, which adds to the installation complexity and cost.
In summary, the Class A Customs 14-Gallon is not for the average RVer seeking a tote, but an essential component for custom builders. It provides a durable, customizable, permanent waste solution for small-scale applications. If you are undertaking a build and need a reliable, compact, fixed black water tank, this is an excellent choice for its quality construction and adaptability. Important: Remember this tank is not a tote and must be properly vented and installed for safe use.

6. RecPro RV 36 Gallon Portable Waste Tank (Blue)
The RecPro RV 36 Gallon Portable Waste Tank is a high-capacity option built for hassle-free use, aimed at those who want a durable, ready-to-use solution for longer excursions. Its large 36-gallon capacity is well-suited for extended dry camping trips, effectively reducing the necessary frequency of dumping. The tank is constructed from heavy-duty polypropylene, which provides excellent resistance to the rigors of travel and the contained waste. A key selling point is that the tank comes pre-assembled with all necessary accessories, saving the user setup time and getting them back to their vacation sooner.
Regarding performance, the tank excels with its dense, non-pneumatic (flat-free) tires, which boast a diamond-pattern tread for superior grip and all-terrain reliability—you’ll never have to worry about airing them up. Furthermore, the built-in capacity indicator and venting cap are excellent features, ensuring you know exactly when the tank is full and facilitating fast, smooth emptying. The large ports also contribute to quick dumping. The only minor drawback is that the handle is a simple tow hook design; while functional for towing, it can be less ergonomic for manually pulling a fully loaded, heavy tank compared to models with oversized handles.
Ultimately, the RecPro 36 Gallon is an extremely competitive choice among the best RV portable waste tanks for its large capacity, flat-free tires, and ready-to-use design. It’s an ideal investment for anyone needing a high-volume, low-maintenance tote. If you prioritize durability, convenience, and a high-capacity system that can handle rough terrain without tire issues, this blue beauty is a fantastic choice.

7. Thetford SmartTote2 RV Portable Waste Tote Tank – 35 Gallon
The Thetford SmartTote2 35-Gallon is renowned for its innovative convenience features that aim to make the entire dumping process quicker and cleaner. This high-capacity, two-wheel model is designed for RVers who value thoughtful engineering and minimal mess. The construction is rugged, and the 35-gallon volume is more than adequate for most extended stays, making it a viable alternative to other large-capacity best RV portable waste tanks. The main target audience is anyone who wants to avoid the fiddly, messy nature of traditional sewer connections and disconnection.
Its standout performance feature is the patented PermaStore system: a self-storing sewer hose that stays permanently connected to the bottom of the tank, pivots out for use, and snaps back in for storage, complete with a bayonet cap to prevent spills. This significantly speeds up setup and tear-down. Moreover, the AutoStop Level Gauge/Valve is invaluable, automatically stopping the flow when the tank is full, eliminating the guesswork and the risk of overfilling. While the two rubber wheels are durable, maneuvering the 35-gallon capacity when full can be physically demanding for one person, as it requires lifting and tilting the weight onto the wheels for transport.
Overall, the Thetford SmartTote2 is one of the best RV portable waste tanks for users who prioritize smart, self-contained features. The AutoStop and PermaStore hose systems genuinely streamline the process. For RVers who frequently use their tote and want to minimize contact with waste, the added convenience features of the Thetford model make it a premium and worthwhile investment despite the heavier manual handling.

8. Class A Customs 27 Gallon RV Waste Black Water Holding Tank
The Class A Customs 27-Gallon tank, like its smaller counterpart, is a permanent fixture designed for installation in RVs, motorhomes, and custom applications, not for portable use. This larger capacity is aimed at full-time RVers or those with mid-to-large sized custom vehicles that require more substantial waste storage than smaller vans or tiny homes. Constructed from the same heavy-duty, one-piece MDPE resin, it guarantees a robust and leak-resistant structure essential for a permanent black water holding tank. It’s a vital piece of the puzzle for a complete RV plumbing system, especially when considering a long-term what is an RV tote tank setup.
Performance in a fixed system relies on its durability and ease of plumbing integration. The tank comes with a pre-installed 3-inch ABS outlet, providing a necessary starting point for professional installation. Its greatest strength is the seamless construction and material that prevents leaks and corrosion. However, the complete lack of fittings for the inlet, vent, and dump valve requires the end-user to source and install them, making the overall process complex and costly. It also necessitates a metal frame for safe mounting, adding another layer of construction effort.
The Class A Customs 27-Gallon is an excellent, durable foundation for a permanent waste system in a larger custom-built RV. It offers reliability and ample capacity for black or gray water, but its purpose is strictly structural, not portable. Buyers should be comfortable with DIY plumbing or plan to hire a professional, as it is a component-only product. For its intended use in custom installations, it is a high-quality, dependable choice.

9. Venustank 30 Gallon RV Portable Waste Tank 2 Wheel Tote Tank
The Venustank 30-Gallon 2-Wheel Tote Tank is a comprehensive, ready-to-use kit offering a great balance of capacity and portability for medium-sized RVers. It is a fantastic option for travelers who need a high-quality tote that comes complete with virtually all the necessary accessories, ensuring minimal hassle and quick deployment at the campsite. The tank itself is made from highly durable, blow-molded HDPE, promising a robust, leak-free, and sun-resistant construction that is designed to withstand frequent use over time.
In terms of performance and mobility, this tote features large, solid rubber back wheels and a 22-inch tow bar, allowing users to easily roll it like a piece of luggage or tow it slowly behind a vehicle. The inclusion of an integrated tank rinser and gate valves facilitates the cleaning and emptying process, ensuring a smooth interior and thorough cleanse. Furthermore, a convenient ladder hook is integrated for secure, simple storage on the side of the RV when not in use. While the tank itself is sturdy, some reviews indicate that a few of the included accessory fittings, such as the dump hose, may be of slightly lower quality and could require an upgrade for the most reliable, leak-proof seal.
Overall, the Venustank 30-Gallon is a high-value product, providing a strong, high-capacity tank with all the essential features and accessories in one package. It is an excellent choice for RVers needing a substantial, yet still manageable, waste tank. For those looking for one of the best RV portable waste tanks that combines a great price point with a durable build and a complete kit, the Venustank is a highly recommended solution.

10. Thetford SmartTote Portable RV Waste Tote Tank – 12 Gallons
The Thetford SmartTote 12-Gallon 2-Wheel tank is the most compact and lightweight option on our list, making it the perfect choice for users with small RVs, van campers, or pop-ups who only need to manage gray water or very small black tank volumes. This model is focused on pure portability and ease of storage. Its small footprint and low weight mean it can be easily stored in tighter compartments, a crucial feature for minimizing clutter in compact living spaces that also need efficient appliances like van life fridges. The durable polypropylene construction is rugged and easy to clean.
The tank’s performance is defined by its simplicity. It comes fully assembled with rubber wheels and a molded-in handle, making it incredibly easy to maneuver and lift by one person, even when full. Furthermore, it incorporates Thetford’s AutoStop Level Gauge, which prevents the frustration and mess of overfilling by automatically stopping the flow. The key consideration, however, is that this specific 12-gallon model is a bare-bones unit: it typically does not include a sewer hose, rinse hose, or the PermaStore system found on its larger counterparts. This means users will need to source their own connecting hose.
In conclusion, the Thetford SmartTote 12-Gallon is an excellent tank if your primary need is maximum portability and minimal weight, especially for managing gray water or short weekend trips. It’s ideal for the minimalist RVer who needs a simple, reliable way to empty smaller tanks without the bulk and weight of a 30-gallon+ model. If compact size and simple manual handling are your top priorities, this is one of the best RV portable waste tanks for you.

How to Choose Best RV Portable Waste Tanks
A portable waste tank is essential for campers who don’t have direct sewer hookups or who frequently enjoy extended dry camping. These tanks, often called “honey wagons,” allow you to drain your RV’s black and gray water tanks and transport the waste to a distant dump station without having to move your entire rig. Choosing the right size and features among the best RV portable waste tanks can dramatically simplify this necessary chore and improve your overall camping experience.
Capacity and Size
Capacity is perhaps the most important consideration. It should roughly match or exceed the capacity of your RV’s black tank. A tank that is too small will require multiple, time-consuming trips. On the other hand, a large, 40+ gallon tank is very heavy when full (upwards of 300 lbs) and may be too bulky to store. Evaluate the duration of your typical trips and the size of your onboard holding tanks to find a Best RV Portable Waste Tanks model that balances capacity with manageable weight.
Wheel Type and Number
The number and quality of wheels significantly affect maneuverability. Two-wheel models are generally more compact and cheaper but require you to lift and balance the full weight on the axle to roll it, which is difficult for large sizes. Four-wheel models, especially those with front-swivel casters, offer superior stability and are much easier to tow or push, even when fully loaded. Look for heavy-duty, no-flat rubber or dense foam tires for all-terrain performance and reliability.
Rinsing and Emptying Features
A clean tote tank is crucial for hygiene and odor control. Essential features to look for include an integrated tank rinser (a built-in port to attach a water hose for internal flushing) and a low drain hole or gate valve. A low drain hole ensures that all residual waste is emptied completely, while a dedicated rinser makes the necessary cleaning process fast and simple. Thetford’s AutoStop feature is a premium option that prevents overfilling and spills.
Towing and Handle Design
Most Best RV Portable Waste Tanks are designed to be rolled manually or towed by a vehicle like a truck or golf cart. If you plan to tow, ensure the tank comes with a steel tow adapter or a dedicated tow bar. For manual rolling, look for an oversized, comfortable, and sturdy handle. The handle should be securely attached and long enough to allow a comfortable pulling posture without the tank hitting your heels.
Material and Construction
The material dictates the tank’s long-term durability. High-density Polyethylene (HDPE) or heavy-duty polypropylene, often blow-molded or UV-stabilized, is the standard. Avoid tanks with flimsy plastic or seams that could burst under the pressure and weight of a full load. Good construction ensures the tank remains leak-free, odor-free, and resistant to sun damage over many camping seasons.
Maintaining Your Best RV Portable Waste Tanks
Proper maintenance is key to keeping your portable waste tank functional and odor-free. Always rinse the tote thoroughly immediately after dumping, ideally using a built-in flushing port if available. A simple rinse with clean water is not enough; routinely add a dedicated RV waste tank chemical or enzyme-based treatment, especially before storage, to break down residual solids and prevent foul odors from building up.
When storing your Best RV Portable Waste Tanks, empty it completely and leave the caps slightly loosened to allow for air circulation. If possible, store it upright or hang it on your RV ladder to maximize campsite space and prevent flat spots on the tires. Finally, inspect all your fittings, caps, and the tow bar periodically for cracks or wear, replacing any compromised parts immediately to prevent a messy disaster during your next dumping trip.
How to Use a Portable Waste Tank
Brief intro, then practical usage steps.
- Setup and Connection: Position the portable waste tank on level ground near your RV’s sewer outlet. Ensure all caps are secure and the tank’s drain valve is closed. Use the shortest necessary sewer hose to connect the RV outlet to the tote tank’s inlet port.
- Core Usage (Dumping): Start by dumping your gray water (sink/shower) first, as this water helps to rinse the connecting hose and clean the solids from the black water dump. Next, open your RV’s black tank valve to let the waste flow into the tote. Once full (or nearly full, using a level indicator), close the black tank valve, and finish by opening the gray tank valve again for a final rinse.
- Optimization and Transport: Disconnect the hose, securely cap the tote tank’s inlet, and ensure the drain valve is tightly closed. If equipped, attach the tow adapter to your vehicle or pull the tote using the handle, keeping your speed low and steady. Once at the dump station, use the tote’s drain valve to empty, then use the integrated rinser (if available) to flush the interior thoroughly.
- Troubleshooting & Pro Tips: Never attempt to tow a fully loaded tank at high speeds, as this is extremely dangerous and can damage the tank. If flow is slow, check to see if the tote requires venting (some models have a dedicated vent cap). Pro tip: always lubricate your gate valves regularly with a silicone spray to ensure smooth opening and closing over time.
Frequently Asked Questions
How full should I fill my Best RV Portable Waste Tanks?
You should aim to fill the portable tank to about 85-90% of its total capacity. This leaves a crucial margin of air space for pressure relief and sloshing during transport. Never fill it completely to the brim, as this significantly increases the risk of spillage and makes the tank dangerously heavy and difficult to manage.
Can I leave my portable waste tank connected to my RV?
It is generally not recommended to leave the tote tank connected indefinitely. While convenient, a long-term connection can create pressure issues and is usually only secure enough for the duration of the transfer. It should be disconnected, emptied, rinsed, and properly stored as soon as the transfer is complete.
What is the difference between a 2-wheel and a 4-wheel portable waste tank?
A 2-wheel tank is more compact and must be tipped onto its wheels and balanced to be rolled or towed, making a full tank physically demanding. A 4-wheel tank offers superior stability, especially the models with front-swivel wheels, allowing a fully loaded, high-capacity tank to be towed or pushed with minimal effort and no manual lifting required.
Are Best RV Portable Waste Tanks primarily for black water or gray water?
Portable waste tanks can handle both black (sewage) and gray (sink/shower) water. However, most RVers use them to prioritize black water, as it’s the most critical to dump. Many also use them for gray water during extended stays to avoid having to break camp for a gray tank dump.
How do I clean the inside of my portable waste tank?
The best method is to use a built-in tank rinser, which allows you to hook up a clean water source to flush the interior after dumping. If your tank lacks a rinser, you can use a garden hose to thoroughly flush water through the main inlet port, then add a cup of vinegar or a specialized chemical to help neutralize odors before final storage.
Final Thoughts
Choosing the right portable waste tank is a crucial step toward hassle-free RVing. It eliminates the frustration of constantly moving your entire rig and provides the freedom to stay off-grid longer. Remember to balance capacity with maneuverability, paying close attention to wheel quality and the inclusion of user-friendly features like integrated rinsers and automatic shut-off valves. A well-chosen tote tank is an investment that quickly pays for itself in convenience and reduced stress on your camping trips.
For most RV owners who need a balance of capacity and portability, the Camco Rhino 36-Gallon Camper/RV Tote Tank offers the best all-around value, including a comprehensive kit and excellent durability. If you operate a large rig or prioritize stability and the smoothest transport possible for a massive capacity, choose the Barker 4-Wheeler Tote Tank – 42 Gallon for its four-wheel stability and minimal manual effort during towing.
