Camco Rhino 15-Gal Portable Tote Tank

It’s best for occasional trips, when RV space is limited, and buyers want a simple, towable tote that’s easy to handle around campgrounds. Caution: smaller capacity means more frequent dumps on longer trips.
RecPro Portable Waste Tank, 36 Gallon

Buying Guide: Portable Waste Tanks For Travel Trailers
Key purchase considerations help buyers choose the right tote tank for their trailer and travel style.
- Capacity vs. frequency of dumps: Higher capacity reduces trips to dumps but increases weight and storage space needs.
- Mobility and stability: Four-wheel designs offer stability on varied terrain; two-wheel systems are lighter and easier to maneuver in tight spaces.
- Ease of cleaning: Look for gate valves and smooth interiors; integrated rinsers simplify maintenance.
- Towability and compatibility: Check tow bars, ladder hooks, and compatibility with your RV ladder or hitch setup.
- Storage considerations: Consider where you will store the tote when not in use; smaller units fit tighter RV storage bays.
Practical Tips And Buyer-Oriented Insights
- Choose best for small- to mid-sized trailers if you have limited storage space.
- Opt for larger capacities if you frequently dry camp or stay away from dump stations for several days.
- Consider stability on soft ground; four-wheel models generally perform better on unpaved surfaces.
- If you tow with a car or small SUV, balance weight and maneuverability to prevent overburdening the vehicle.
- Plan for cleaning: a tote with an integrated rinser saves time after dumps.
