Camco Rhino 15-Gal RV Portable Tote Tank
Best for travelers who need a compact waste-transfer tote that’s easy to move and tow. The 15-gallon tote is designed for transporting waste from RV black tanks to dump stations when hoses can’t reach. It features no-flat wheels for reliable maneuvering on varied terrain, a large handle for control, and a steel tow adapter for towing behind a vehicle or golf cart. Constructed from UV-stabilized HDPE to resist sun and weather exposure, this tank is built for outdoor use.
Who it’s best for: RV owners who park far from dump stations or require a portable waste-transfer option without a full-size tote. Why selected: strong wheels, tow-capable design, and durable material. Caution: limited capacity means more frequent trips for larger crews.

This tank is ideal for RVs that prioritize moderate storage with flexible installation. Made in the USA from BPA-free materials, it’s designed for potable water use—suitable for drinking, cooking, cleaning, and showering. Built-in fittings include multiple threaded ports to accommodate various install layouts, and the tank’s weather- and impact-resistant plastics support durability and hygiene. It meets IAPMO standards for safe water storage.
Who it’s best for: RVers seeking a mid-sized, American-made potable water tank with install versatility. Why selected: BPA-free, durable construction, and standard fittings. Caution: installation options may require extra fittings or hardware depending on the RV model.

Best for expanding water capacity without frequent refills. The larger 57-gallon tank is built from weather- and impact-resistant plastics and is designed to be sanitary and leak-proof. Like the 36-gallon model, it includes multiple connection ports (two 1.5″ NPT and two 0.5″ NPT) for flexible installation options and meets IAPMO standards.
Who it’s best for: larger RVs, full-timers, or families needing substantial potable water storage. Why selected: higher capacity helps reduce refill frequency. Caution: larger size may require more underbelly or cabinet space for installation.

Who it’s best for: RV owners who value an included pump and plumbing in one package. Why selected: convenience of a kit, ready-to-use plumbing. Caution: the kit adds components that may require wiring and setup familiarity.
Water Bladder Portable Water Tank
Best for flexible, emergency-ready storage. This collapsible bladder is designed for camping, gardening, and disaster readiness. Made from thick, reinforced PVC with high-strength seams, it folds for compact storage when not in use and can be deployed quickly when water is needed. It’s temperature-tolerant and suitable for a wide range of outdoor conditions.
Who it’s best for: campers and emergency-prepared households needing foldable storage. Why selected: portability and collapsibility. Caution: not a rigid tank; requires careful handling to prevent punctures and ensure long-term integrity.
Buying Guide: Key Considerations for Portable RV Water Tanks
- Capacity vs. space: Larger tanks provide more water but require more mounting space and weight. Choose capacity based on travel duration and crew size.

- Installation options: Consider tanks with multiple ports and compatible fittings. Check whether you need built-in pumps, plumbing kits, or adapters.
- Portability and handling: If you need to move tanks regularly, prioritize wheels, handles, and towing compatibility. For emergency storage, collapsible designs save space.
- Standards and compliance: IAPMO or equivalent standards indicate adherence to sanitation and safety guidelines for potable water tanks.
- Maintenance: Choose smooth interiors and leak-proof seals to minimize cleaning effort and reduce contamination risk.
