10 Best Portable Rv Septic Tank 2026 in the United States

The Camco Rhino Portable RV Waste Holding Tank is a solid choice for RV owners needing to transport waste to dump stations. With a 36-gallon capacity, it’s designed to handle the waste needs of most RVs and trailers. One of its key strengths is its ease of transport; the large, no-flat wheels and removable steel tow adapter allow for smooth movement, whether you're pulling it behind a vehicle or rolling it like a suitcase. Its construction from high-density polyethylene (HDPE) ensures durability and resistance to punctures, which is essential for this type of product.

This tank is equipped with several accessories that enhance its usability, including a tank rinser for easy cleaning and multiple hoses for versatile connections. The built-in gate valve also simplifies the emptying process, making it user-friendly for those who may not be very experienced with RV waste management.

While the tank's weight of approximately 44.9 pounds is manageable, it can be cumbersome for some users, especially when full. Although it is portable, lifting it may still pose a challenge for those with limited strength. Additionally, even though the included accessories are beneficial, some users may find they need additional parts for specific setups, which could lead to extra expenses.

The Camco Rhino 28-Gallon RV Tote Tank is designed to make waste disposal easier for RV users, especially when the campsite's dump station is too far for your RV’s sewer hose. It has a good capacity of 28 gallons, which is generally enough for a few days of use, depending on your RV size and usage. Made from durable, UV-stabilized high-density polyethylene, it holds up well against outdoor conditions without leaking or sun damage.

The tank’s portability is enhanced by its two large no-flat wheels that handle rough terrain easily, an oversized handle for comfortable pulling, and a steel tow adapter that lets you tow it behind a vehicle or golf cart, saving you effort. Connection options are versatile, including a 3-foot sewer hose with swivel fittings and several caps and elbows, making it compatible with various RV systems. The built-in gate valve and smooth interior help with quick emptying and easy cleaning, which is a big convenience. Storage is also simple thanks to the ladder hook and tie-down grooves.

The tank weighs 43 pounds empty, which might feel a bit heavy to some users when fully loaded, and the 28-gallon capacity, while sufficient for many, may be limiting for larger RVs or longer trips without dump access. The kit is well-equipped, but setup and use might need some initial familiarization for first-time users. This tote tank represents a reliable, portable waste solution combining durability, ease of movement, and helpful accessories for RV owners.

The Camco Rhino 15-Gallon Portable RV Tote Tank is designed to make waste disposal from your RV convenient and hassle-free. It offers a decent 15-gallon capacity which is suitable for short to medium trips. The tank is made from durable, UV-stabilized blow-molded HDPE, ensuring it can withstand the rigors of outdoor use without suffering from leaks or sun damage.

The large, heavy-duty no-flat wheels and oversized handle make it easy to transport, even over rough terrain. The inclusion of a removable steel tow adapter allows for effortless towing behind a vehicle, adding to its portability. Compatibility is well-addressed with the 3’ sewer hose and various fittings included, ensuring it can connect to most RV setups.

Users will appreciate the low drain hole for thorough emptying and the integrated tank rinser which simplifies cleaning. However, the tank's weight of 31.5 pounds might make it cumbersome for some users to handle alone. Also, while the large wheels are beneficial, they might take up additional storage space. This product is ideal for RV owners who frequently find themselves parked far from dump stations and need a reliable, portable solution for waste disposal. With a sturdy build, it appears to be a dependable choice in the portable RV septic tank category.
