Camco Rhino 21-Gallon Portable Waste Tank
Camco’s Rhino line emphasizes portable waste management with rugged, no-flat wheels and a low drain hole. The 21-gallon model is compact but demonstrates the design philosophy applied to larger totes: durable UV-stabilized HDPE construction, a substantial handle, and a steel tow adapter for towing behind a vehicle. It is ideal when the RV’s sewer hose cannot reach the dump station, providing a practical solution for longer gaps between the rig and the disposal point. The included accessory bundle expands usability for roadside stops and remote campgrounds.
Camco Rhino 36-Gallon Portable RV Tote Tank
This model increases capacity to 36 gallons while keeping the core Camco design cues: steerable front wheels, large back wheels for varied terrain, and a robust steel tow adapter. The tote is constructed from UV-stabilized HDPE, ensuring weather resistance for outdoor use. A built-in gate valve and easy curb-to-dump operation are complemented by a wide overall footprint, which stabilizes the unit during transport. This option strikes a balance between capacity and maneuverability for longer trips or larger RVs.
Venustank 39 Gallon RV Portable Waste Tank (2 Wheel)
The Venustank 39-gallon tote emphasizes a ready-to-use kit, including accessories for cleaning and maintenance. Its two-wheel design supports straightforward rolling, with a 22-inch tow bar that enables flexible transport options—roll behind a vehicle or tow with a golf cart. The tank is built for easy cleaning with a smooth interior and a gate valve that facilitates complete emptying. This option suits users seeking a higher-capacity solution without sacrificing mobility.
Venustank 30 Gallon RV Portable Waste Tank (4 Wheel)
This Venustank model offers a four-wheel design for stable handling and smooth transitions across uneven surfaces. Paired with a 24-inch tow bar, it provides flexible towing options and easy maneuverability. The kit includes essential accessories for cleaning and maintenance, and a smooth interior assists with effortless cleaning. The capacity is practical for many recreational vehicle setups, and the larger wheelset helps manage varied campground terrain.
YITAHOME 19.8 Gallon Large Capacity Portable Water Holding Tank
While primarily a water holding tank, this model shows how capacity-focused totes can adapt for varied needs around RVs. It highlights a large capacity and multiple water injection and drainage outlets for efficient filling and emptying. A level indicator helps monitor content levels to prevent overflows. This option illustrates how compatible features in beverage and water totes can translate to waste-tank design considerations for users who value visibility and control.
Camco Rhino 15-Gallon Portable RV Tote Tank
The 15-gallon model presents a more compact option with the same brand emphasis on ease of transport. It features large heavy-duty no-flat wheels and a low drain hole, plus a steel tow adapter and a 3-foot sewer hose. This size is ideal for smaller RV setups or for users who prioritize lighter equipment while still receiving the benefits of Camco’s reliable design and accessories.
Buying Guide: Key Purchase Considerations
- Capacity versus vehicle reach: If your dump station is frequently far away, a larger tank reduces the number of trips. Balance capacity with the ability to maneuver the unit around campgrounds and tight spaces.
- Wheels and mobility: No-flat or solid rubber wheels, steerable front wheels, and a sturdy handle improve maneuverability over uneven terrain. Consider whether you’ll tow behind a vehicle or push manually.
- Materials and durability: UV-stabilized HDPE or similar plastics resist sun exposure and outdoor conditions. Check for reinforced corners and leak-proof fittings to prevent spills.
- Ease of emptying: Large ports, gate valves, and smooth interior surfaces simplify draining and cleaning. A reliable drain system reduces cleanup time at the dump station.
- Accessories and compatibility: Kits that include hoses, valve kits, and tank rinser accessories add value, especially if you RV frequently camps in remote areas without hookups.
- Weight and storage: Heavier totes can be stable but harder to transport. Ensure the storage area in your RV can accommodate the tank when not in use.
- Maintenance considerations: Choose models with rinse- and cleaning-friendly interiors, and look for components that resist wear from frequent use and outdoor exposure.
- Warranty and support: Longer warranties indicate confidence in durability. Confirm return policies and replacement parts availability in case of wear or damage.
These options present a spectrum of capacities and configurations to fit different RV sizes, travel styles, and campground layouts. Consider your typical travel distance to dump stations, towing capabilities, and how much you value ease of use and maintenance when selecting a model.
