1. Camco Rhino 21-Gallon RV Portable Waste Tank – Features Large Heavy-Duty No-Flat Wheels & Low Drain Hole – Includes Removable Steel Tow Adapter, 3’ Sewer Hose & More RV Accessories (39002)

When I first came across the Camco Rhino 21-Gallon RV Portable Waste Tank, I immediately recognized how it could transform the way I manage waste disposal during my RV trips. The very fact that it’s designed to simplify waste disposal resonates with anyone who has struggled with the distance between their RV and dump stations. This tank makes hauling waste from the black water tank to the dump station so much easier, especially when your RV sewer hose can’t quite reach. For me, that convenience alone justifies serious consideration, especially if you frequently camp in areas where connections aren’t close by.

What impresses me most about this product is how effortless it makes transport. The large, heavy-duty no-flat wheels are built for any terrain, so I don’t have to worry about navigating rough or uneven ground. The oversized handle enhances maneuverability, and the removable steel tow adapter means I can tow the tank behind a truck or even a golf cart without any hassle. This versatility in transport options means less strain and more convenience, something I genuinely appreciate when managing heavy loads. It’s clear that Camco designed this tank with the user’s comfort and ease of use in mind.

Durability is key for any RV accessory, and this 21-gallon tank truly delivers. Constructed from UV-stabilized blow-molded HDPE, it’s built to withstand the rigors of outdoor use, sun exposure, and the wear and tear of regular handling without cracking or leaking. Weighing just 34.5 pounds, it strikes a good balance between sturdiness and portability. Knowing that it’s made in the USA with a patented design adds an extra layer of trust in its quality and craftsmanship. For me, investing in a product that promises longevity and reliability is always a smart choice.

Camco thoughtfully equipped this tote tank with features that enhance functionality and ease of use. The inclusion of two oversized wheels, a large handle, a tank rinser, and a ladder hook means I have everything I need to operate and maintain the tank efficiently. The integrated tank rinser, in particular, stands out as a thoughtful touch since it allows for thorough cleaning with minimal effort. Cleaning waste tanks can be a dreaded chore, but this design makes it manageable and less unpleasant. Plus, the ladder hook lets me store the tank conveniently on my camper ladder, freeing up space inside the RV.

The kit’s comprehensive accessory package is another compelling reason I find this product appealing. It comes with a 3-foot sewer hose with swivel fittings, a 15-inch female/female grey water hose, a clear elbow with a 4-in-1 fitting, a clear double bayonet elbow, multiple storage caps, and the steel tow adapter. Having all these components included means I won’t have to buy additional parts separately, saving time and money. It also ensures compatibility and ease of setup, which is crucial when you want things to work smoothly without guesswork.

Finally, the ease of cleaning and storage really rounds out this tank’s practical appeal. The drain hole allows for complete emptying, and the smooth interior surface helps prevent residue buildup, making maintenance straightforward. The ability to compress the 3-foot sewer hose and store the tank securely with tie-down straps in built-in grooves means I can keep my RV area neat and organized.

Buying Guide for Portable Gray Water Tank

Understanding What a Portable Gray Water Tank Is

When I first looked into managing gray water during camping trips or RV travel, I realized a portable gray water tank is essentially a container designed to collect and store used water from sinks, showers, and other non-toilet sources. Knowing this helped me understand its importance in environmentally responsible water disposal and in complying with local regulations.

Considering Tank Capacity

One of the first things I considered was the size of the tank. Portable gray water tanks come in various capacities, typically ranging from 10 gallons to over 40 gallons. I had to think about how long I would be away from dumping facilities and how many people would be using the water, so I could choose a size that would last without being too bulky.

Material and Durability

I paid close attention to the materials used in the tank’s construction. Most are made of durable plastic like polyethylene, which is resistant to corrosion and easy to clean. Since I planned to use mine outdoors, I wanted something sturdy enough to handle rough terrain and frequent handling without cracking or leaking.

Portability Features

Because I needed to move the tank easily, features like wheels, handles, and compact design were important. I looked for tanks with sturdy wheels that could roll over uneven surfaces and comfortable handles for lifting. A design that balanced size with ease of transport made a big difference in my experience.

Ease of Emptying and Cleaning

I wanted a tank with a simple valve or spout system to make emptying the gray water hassle-free. A well-designed drain valve reduced spills and made the process quick. Additionally, tanks that were easy to clean helped me maintain hygiene and prevent unpleasant odors.

Compatibility with My Setup

I checked whether the tank would fit well with my existing RV or camping setup. This included the size and shape to fit in storage compartments and the connection fittings to attach hoses securely. Ensuring compatibility saved me from having to buy extra adapters or dealing with leaks.

Legal and Environmental Considerations

I researched local laws regarding gray water disposal because some areas have strict rules. Having a portable gray water tank helped me follow regulations by safely storing water until I could dispose of it at designated dump stations, minimizing environmental impact.

Budget and Value

Finally, I balanced the cost with features and quality. While I didn’t want to overspend, I found that investing in a reliable, well-built tank paid off in convenience and longevity. Looking for good reviews and warranties gave me confidence in my purchase.

Final Thoughts

Buying a portable gray water tank was a game-changer for my outdoor adventures. By considering capacity, durability, portability, ease of use, and legal factors, I was able to select a tank that met my needs and made gray water management simple and responsible.
