Camco Rhino Tote Tank for RV Waste
The Camco Rhino 36-Gallon Tote Tank is designed to simplify waste disposal when RV hookups are unavailable or out of reach. Its large, rugged wheels enable easy transport across uneven terrain, while a built-in gate valve supports straightforward connection to disposal lines. The included steel tow adapter allows towing behind a vehicle or golf cart, enhancing maneuverability for campsites or parking lots where access is limited. Constructed from UV-stabilized HDPE, the tank is meant to endure outdoor conditions and repeated use without leaking or sun damage. With dimensions around 15.5″ by 25″ by 46″ and a weight near 45 lb, it balances capacity with portability. This unit is suitable for travelers who want a reliable way to move waste from a distant black water tank to a dump station without immediate sewer access.
Key features include: portable waste transfer, no-flat wheels for all-terrain use, an oversized handle, and a tow adapter for easy hauling. The 36-gallon capacity provides ample storage for multiple days on longer trips, and the sturdy construction supports extended outdoor use. This model is best for RV owners who frequently encounter dump stations that are far from the campsite.
YITAHOME 19.8 Gallon Water Tank
The YITAHOME portable water holding tank offers a higher-capacity option for fresh or gray water needs on the go. With a 19.8-gallon (75 L) capacity, this tank makes it easier to transfer water between your RV and distant refill points. A notable advantage is the built-in handle and large universal wheels, which support easier transport. Multiple water injection and drainage outlets streamline filling and emptying cycles, and a level indicator helps operators know when to dump or retop off, reducing the risk of overflows. This tank is well-suited for campers who want to minimize frequent trips to refill water or drain waste while on the road.
Highlights include: broad capacity, simplified filling and draining options, and a display for monitoring water level. The design focuses on ease of transport and practical use in busy camping environments, making it a practical choice for families and long trips where water management matters.
A.A Fresh & Gray Water Tank Combo
This BPA-free set includes a 10-gallon fresh water tank and a 16-gallon gray water tank, both rotationally molded from durable polyethylene. The one-piece seamless construction minimizes the risk of leaks and seams that could fail under pressure. The compact profiles fit into tighter spaces in RVs or trailers, making them a practical choice for smaller rigs where storage space is at a premium. Installation requires attention to inlet, outlet, and vent connections, with appropriate fittings and piping per the user’s configuration. The pair provides a simple solution for owners who need separate tanks for clean water and gray waste while keeping costs reasonable.
Important considerations: compatibility with standard RV plumbing fittings, potential need for additional hardware, and ensuring proper venting to prevent airlocks during use. The pair is apt for travelers who want reliable, non-drinking water storage without taking on a large, integrated system.
RecPro 30 & 42 Gallon Water Tanks
The RecPro combo pack includes two tanks with capacities of 30 gallons and 42 gallons, designed for fresh or gray water storage. These rotationally molded tanks are made in America and NSF approved, ensuring safety and durability for potable water storage in correct applications. Typical features include standard inlet fittings (2″ long), and a 7/8″ internal diameter, smooth barrel for consistent water flow. This option is advantageous for campers seeking a larger water reserve or a two-tank arrangement to separate potable water from gray waste in a compact system. As with any tank, proper venting and secure connections are essential for reliable operation.
Considerations include ensuring compatibility with your RV’s pump and plumbing, verifying inlet/outlet sizes, and planning for secure mounting to minimize movement while traveling. The larger 42-gallon option is ideal for extended trips where access to refill points is limited.
classAcustoms WT-1653 16 Gallon Black Water Tank
The WT-1653 is a 16-gallon black water waste holding tank designed for RVs, campers, and trailers. It uses MDPE resin and is intended specifically for waste water, not for fresh or drinking water. The tank features an installed 3″ ABS outlet and should be vented to function correctly during use. Installation requires careful planning for inlet, outlet, and vent locations, with hardware and fittings chosen by the installer. The product is positioned for users who need a dedicated waste tank with a robust, USA-made build and a straightforward upgrade path for existing RV systems.
Trade-offs to consider include the need for compatible piping and venting strategies, potential additional fittings, and ensuring that the tank’s dimensions fit the available space in the vehicle. This model is suitable for RVers who want a dedicated waste storage solution without mixing with fresh water systems.
Buying Guide: Key Purchase Considerations For Camper Water Tanks
- Capacity vs. space: Select a tank size that aligns with your travel style, daily water use, and available storage space in your RV. Larger tanks reduce refill needs but take up more room.
- Water type: Distinguish between fresh, gray, and black water tanks. Fresh water tanks must be BPA-free and potable-safe, while black water tanks must be compatible with waste discharge systems and venting.
- Material durability: Look for UV-stabilized HDPE or MDPE for outdoor exposure and long-term use. Seamless or one-piece constructions reduce leak risks.
- Accessibility: Consider tanks with easy-to-use inlets, outlets, and level indicators. Some units feature built-in handles or wheels to simplify transport and installation.
- Ventilation: Proper venting is essential, especially for waste tanks and larger capacity tanks, to prevent pressure buildup and odors.
- Installation compatibility: Verify inlet/outlet sizes and fittings (for example, 1.25″ or 1.5″ NPT) and ensure that the tank can be integrated with your RV’s plumbing layout and pump system.
- Weight and mounting: Heavier tanks require reinforced mounting and secure fastenings to prevent movement during travel. Consider whether a tank’s footprint fits behind storage panels or in exterior compartments.
- Maintenance: Choose tanks with smooth interiors and accessible drain ports to facilitate cleaning and winterization. Some models offer easier cleaning via multiple outlets or removable components.
- Warranty and availability: Check manufacturer warranties and customer service options, especially for large or mission-critical components like waste tanks.
When evaluating options, align product features with your camping style: weekend travelers may prioritize portability and ease of transport, while full-timers might favor larger capacities and integrated fittings. Consider future needs, such as potential expansion to a dual-tank setup or moving to a larger RV with different plumbing configurations. Robust build quality, compatibility with standard RV fittings, and reliable venting are central to selecting tanks that minimize maintenance and environmental risk while maximizing on-road comfort.
