Camco Rhino 21-Gallon Portable Waste Tank
The Camco Rhino 21-Gallon Portable Waste Tank combines portability with rugged durability. Its large, heavy-duty no-flat wheels provide reliable transport across varied terrain, making it ideal for distant dump stations. A prominent oversized handle enhances maneuverability, and a steel tow adapter enables towing behind a truck or golf cart, simplifying disposal when your RV sewer hose can’t reach. Dimensions measure 20 1/8″ L x 12 1/2″ W x 40″ H, with a weight of 34.5 lb. Constructed from UV-stabilized HDPE, this tank resists sun damage and leaks, ensuring long-lasting outdoor use. Ideal for RVers who frequently need to haul waste over uneven ground or longer distances.
Key considerations: Large capacity can reduce trips to the dump station, but the weight when full requires solid handling. The tow adapter improves versatility for towing options. Maintenance is straightforward with a durable material that’s resistant to environmental wear.
Camco Rhino 36-Gallon Tote Tank
This larger Rhino 36-Gallon Tote Tank is built to handle extended trips or higher waste volumes. It features heavy-duty no-flat wheels for versatile movement and a built-in gate valve for controlled dumping. The included removable steel tow adapter enables simple towing behind a vehicle, making it practical for campsites without direct sewer access. With dimensions around 15 ½” L x 25″ W x 46″ H and a weight of 45 lb, it is constructed from UV-stabilized HDPE to withstand outdoor exposure. A balanced combination of capacity and stability makes this model suitable for full-timers or families that accumulate more wastewater during trips.
Considerations: The larger footprint requires more storage space. Ensure your tow vehicle and hitch setup can accommodate towing a heavier tank when loaded. UV resistance helps longevity in sunny climates.
Camco Rhino 15-Gallon Portable Tote Tank
The 15-Gallon Rhino Tote Tank offers a compact option for RVers who prioritize lightweight transport and easy storage. It features large no-flat wheels for stable movement and a low drain hole to simplify emptying. The accompanying steel tow adapter enhances towing capabilities for transport to distant dump stations. This tank weighs approximately 31.5 lb and measures 20 1/8″ L x 12 1/2″ W x 32 1/8″ H, making it a space-efficient choice for smaller trailers or occasional use. Durable HDPE construction ensures resilience against weather-related wear.
Considerations: Ideal for lighter use or nearby dump stations. If you regularly generate substantial waste, a larger model may reduce trips but increase storage and handling requirements.
Venustank 30 Gallon Portable Waste Tank
The Venustank 30 Gallon Portable Waste Tank focuses on ease of movement and flexibility. It is equipped with large back wheels made of solid rubber to smooth transportation, and a 22-inch tow bar allows rolling like a suitcase or towing behind a truck or golf cart. The interior is designed to simplify cleaning with a gate valve arrangement and an integrated tank rinser. A ladder hook provides secure storage when not in use. This model balances high capacity with maneuverability, making it a strong option for longer trips with minimal access to dump stations.
Considerations: Ensure you have a compatible hitch setup for towing and a secure method for storing the tank when not in use. The integrated rinser aids cleaning but regular maintenance is still recommended to prevent clogs and odors.
classAcustoms 28 Gallon RV Waste Tank WT-2800
The WT-2800 from classAcustoms is a 28-gallon holding tank designed for black water and gray water use in RVs, campers, trailers, motorhomes, and tiny houses. It is manufactured in the USA using MDPE resin, emphasizing durability and local production. The unit features an installed 3″ ABS outlet with a fixed position, requiring the user to determine inlet and vent placements. The design discourages pressurization and over-tightening of fittings to prevent damage. While the included hardware doesn’t cover every installation scenario, the tank’s rugged construction and stated suitability for black water waste make it a robust choice for many RV configurations.
Considerations: Check compatibility with your current plumbing setup and plan for inlet/vent placement. Consider whether you need additional fittings or valves not included with the tank. The USA-made aspect may appeal to buyers prioritizing domestic manufacturing standards.
Buying Guide: Key Purchase Considerations For RV Waste Water Tanks
- Capacity and frequency of use: Larger tanks reduce trips to dump stations but require more storage space when not in use. Assess typical trip length and crew size to pick the right capacity (15–36 gallons are common options).
- Mobility and handling: Heavy loads demand sturdy wheels, a wide wheelbase, and a comfortable tow handle. No-flat tires and a robust tow adapter are important features for off-p pavement or remote sites.
- Material durability: UV-stabilized HDPE or MDPE resins resist sun exposure and outdoor weather. Durable construction minimizes leaks and long-term maintenance.
- Dumping mechanism: Look for convenient drain holes or built-in gate valves, and consider whether an integrated tank rinser or an external hose port is desirable for cleaning.
- Portability vs. permanence: Portable tote tanks suit mobile RV life and frequent relocation, while larger stationary tanks suit long-term setups at a single site. Ensure storage space at the rig or campsite is adequate for your choice.
- Installation needs: Some tanks require specific inlet/vent venting and hardware not included. Plan for compatible fittings, piping, and valves to avoid installation issues.
- Maintenance and odor control: Materials that resist odors and easy cleaning features (like interior rinsing) help keep rigs more pleasant during and after use.
- Manufacturer reliability and support: Brand reputation and availability of replacement parts or accessories (towing adapters, hoses, vents) influence long-term satisfaction.
Choosing the right RV waste water tank involves balancing capacity, portability, durability, and ease of use. By focusing on tanks with sturdy wheels, durable materials, and user-friendly dumping mechanisms, you can minimize the hassle of waste disposal on and off the road. Always verify compatibility with your RV’s plumbing and storage constraints before purchase to ensure a seamless fit and reliable performance on the road.
