Brand: Camco
A reliable, compact tote for RVers who need easy waste transport.
The Camco Rhino 21-Gallon tote tank is a solid choice for RVers who need a balance of capacity and portability. Its blow-molded HDPE construction is UV-stabilized, so it won’t degrade in the sun, and it’s built to handle outdoor abuse. The no-flat wheels roll smoothly over gravel, grass, and pavement, while the oversized handle and steel tow adapter make it easy to pull behind you or attach to a vehicle.
Weighing just 34.5 pounds, this tank is manageable for most users. The patented design is made in the USA, ensuring quality craftsmanship. If you have a smaller RV or only need to empty a black tank occasionally, this 21-gallon size is a practical middle ground between the 15 and 36-gallon models.

Camco Rhino 36-Gallon Tote Tank – Steerable and Spacious
The Camco Rhino 36-gallon model takes convenience up a notch with two steerable front wheels that make maneuvering around campsites a breeze. The large back wheels handle rough terrain, and the oversized handle plus steel tow adapter allow you to tow it behind your RV or vehicle effortlessly. This tank is built from the same durable, UV-stabilized HDPE as the smaller Rhino models, so it’s tough enough for years of use.
Weighing 55 pounds, it’s heavier when empty, but the wheel design compensates by distributing the load. The included 3-foot sewer hose and gate valve simplify the emptying process. If you have a larger RV or frequently camp without full hookups, this 36-gallon capacity means fewer trips to the dump station.

The compact dimensions (20 1/8″ L x 12 1/2″ W x 32 1/8″ H) make it easy to store in an RV compartment or even in a car trunk.
Despite its smaller size, it still features the oversized handle and steel tow adapter for effortless transport. This tank is perfect for quick trips to the dump station or for RVers with limited space. The patented design and USA manufacturing add to its appeal, giving you peace of mind in terms of quality.

Made from durable polymer material, it’s built to last. If you want to avoid guesswork and potential spills, this gauge is a smart addition to your setup.

- Requires compatible tank
Buyer’s Guide: What to Consider
Choosing the right portable waste tank involves balancing capacity, ease of transport, and durability. Here are five key factors to consider before making your purchase.
- Capacity: Consider how much waste your RV produces. Smaller tanks (15-21 gallons) are lighter and easier to store, while larger tanks (30-39 gallons) reduce dump trips. Choose based on your RV's tank size and how often you camp off-grid.
- Wheel Design: Two-wheel tanks are simpler and lighter, but four-wheel models with steerable front wheels are easier to maneuver, especially when full. No-flat tires are a plus for rough terrain. Think about where you'll be towing the tank.
- Build Material: Look for tanks made of high-density polyethylene (HDPE) or polypropylene. These materials are UV-stabilized and resistant to cracking, ensuring durability in outdoor conditions. Check for reinforced seams and leak-proof construction.
- Included Accessories: Some tanks come as complete kits with sewer hoses, bayonet fittings, and tow bars, while others are bare tanks. Consider what you already own and what you need. A tank with a gate valve and rinser makes cleaning easier.
- Portability and Storage: Weight and dimensions matter. Heavier tanks are harder to lift, but they often have better wheels. Also, think about where you'll store the tank when not in use. Some models have ladder hooks or compact designs for easy storage.
Conclusion
Portable waste tanks are a game-changer for RVers who want flexibility in where they camp. Whether you need a compact 15-gallon tank for quick trips or a 39-gallon behemoth for extended boondocking, there’s a model that fits your needs. The Camco Rhino line offers reliable, USA-made options, while Venustank provides complete kits with convenient features like steerable wheels and tank rinsers.
For most RVers, the Camco Rhino 36-gallon with steerable wheels is an excellent all-around choice, but if you need maximum capacity, consider the Venustank 39-gallon 4-wheel model. Don’t forget accessories like the Chapou fill gauge to make waste management even easier. Happy camping!
