Camco Rhino 21-Gallon RV Portable Waste Tank - Heavy-Duty Wheels

In this review the Camco Rhino 21-Gallon RV Portable Waste Tank is evaluated for campers and RV owners who need a reliable, easy-to-move solution for emptying black water tanks when sewer hookups are out of reach. The biggest reason to buy is its practical combination of a durable, UV-stabilized blow-molded HDPE body and large no-flat wheels that make transporting up to 21 gallons of waste over uneven terrain far less of a chore than using a flimsy bucket or dragging a hose. It comes as a kit with hose pieces and a steel tow adapter so users have what they need for most dump situations.

Key Features

• Portable 21-gallon capacity: Holds a substantial amount of waste for most weekend trips while remaining compact enough to maneuver and store on a camper ladder.
• No-flat heavy-duty wheels: Oversized wheels let users pull the tank across gravel or grass without worrying about punctures or frequent wheel maintenance.
• Durable construction: UV-stabilized blow-molded HDPE resists sun damage and outdoor exposure so the tank stays leak-free and serviceable season after season.
• Complete accessory kit: Includes a 3' sewer hose with swivel fittings, grey water hose, elbow fittings, storage caps, and a steel tow adapter to cover common hookup and towing needs right out of the box.
• Easy cleaning and draining: A low drain hole, smooth interior and integrated tank rinser make flushing and draining the tank straightforward and sanitary.

Who It's For

The Rhino 21-gallon tote tank suits weekend RVers, couples or small families who park away from dump stations and need a portable, reliable holding solution that can be transported by hand or towed behind a golf cart or truck. Its wheels and handle reduce strain for users moving tanks across campsites or unpaved lots.

Those who should look elsewhere include travelers who require larger capacity for extended off-grid stays or users prioritizing ultralight gear, since the tank weighs about 34.5 lb when empty and is built for durability rather than minimal weight.

Pros & Cons

Pros

• Well-constructed HDPE body resists UV and outdoor wear for lasting use.
• Heavy-duty no-flat wheels and oversized handle make transport across terrain easy.
• Comes with a broad accessory kit including swivel hose and steel tow adapter for towing convenience.

Cons

• Some users report handle durability issues, so heavy or frequent towing may stress the grip or connections.
• The empty weight is substantial, which may be a consideration for solo users when lifting.
