Camco Rhino 36-Gallon Tote Tank
The Camco Rhino 36-Gallon Tote Tank is designed for serious disposal needs on longer trips or when access to dump stations is limited. Best for full-timers or seasonal travelers who need to haul waste from the RV’s black water system to a distant dump site. The unit weighs about 45 lb and measures 24 1/8” L x 14 3/4” W x 44 7/8” H, built from UV-stabilized HDPE for outdoor resilience. Its no-flat wheels and oversized handle prioritize stability on uneven surfaces, while a steel tow adapter supports towing behind a vehicle. A potential limitation is its size and weight when fully loaded, which may complicate handling in tight spaces.
Camco Rhino 28-Gallon Tote Tank
The Camco Rhino 28-Gallon Tote Tank emphasizes portability with no-flat wheels and a steel tow adapter, making it a strong fit for mid-length trips where the dump station is not immediately reachable. It weighs about 43 lb and measures 14 ½″ (L) x 24″ (W) x 44″ (H). This option is better for campers who want a balance between capacity and maneuverability. Its main caveat is that mid-range capacity may require more frequent emptying on frequent travel days.
Camco TST RV Grey Water Odor Control
This lemon-scented odor control is designed to neutralize grey-water odors in RV systems. It’s best for buyers seeking a simple, ready-to-use solution to minimize smells during travels and campground stays. The product is formulated to be septic-tank-safe and formaldehyde-free, reducing environmental concerns. A limitation is that it does not provide direct tank capacity; rather, it supports odor management for grey-water lines and tanks.
ADIOS! Grey Water Tank Cleaner & Enzyme Deodorizer
ADIOS! offers a 32 oz enzyme-based cleaner designed to maintain grey tanks by breaking down organic waste and preventing grease buildup. It’s positioned as a maintenance product that continuously digests waste to reduce odors and improve flow in pipes. The enzyme approach is a good fit for regular travelers who want ongoing tank health. A potential limitation is the cost per use compared to single-use treatments, depending on frequency of tank cleaning.
Camco Rhino 21-Gal Portable Tote Tank
The Camco Rhino 21-Gal Tote Tank is a lighter option for quick trips or smaller RVs. It’s best for travelers who need a compact, easy-to-maneuver tote with adequate capacity for shorter stays. The unit includes no-flat wheels and a steel tow adapter, ensuring stability and towing ease. The trade-off is smaller capacity, which requires more frequent emptying on longer itineraries or with higher grey-water output.
Buying Guide: Practical Pick-Your-Solution Guide
What size tote tank should I choose?
Choose a capacity based on travel frequency, campground access, and tank discharge distance. Larger tanks (like 36 gallons) reduce trips to dumps but are heavier to move. Smaller tanks (21–28 gallons) are easier to handle but require more frequent disposal on longer trips.
Are wheels and towing features important?
Yes. Wheel quality and a sturdy tow adapter improve transport on uneven surfaces and through RV sites. No-flat wheels reduce the risk of a flat during travel, while a tow adapter makes dressing down and hitching easier.
What about odor control and maintenance?
Odor-control treatments help when you’re parked in close campsites or have limited ventilation. Enzyme-based cleaners support ongoing tank health by digesting organic material, reducing build-up and clogs.
Are these products safe for septic systems?
Most listed odor-control and cleaning agents are designed for RV grey-water systems and safe for septic use when used as directed. Always follow the manufacturer’s instructions for the best results and environmental protection.
How should I store and transport these totes?
Store in a shaded area to minimize UV damage. Ensure wheels are in good condition and the tote is secured to prevent tipping during movement or towing.
