Camco Rhino 21-Gallon RV Portable Waste Tank
The Camco Rhino 21-Gallon Portable Waste Tank helps simplify black water disposal by letting you move waste from the RV to a dump station even when the hose can’t reach. It’s best for small to mid-sized RV setups where compact storage and straightforward towing are priorities.
- Best for: RVers with limited space or shorter trips who still need a reliable dump solution.
- Why selected: Large, heavy-duty wheels and a steel tow adapter enable smooth towing behind a vehicle or golf cart.
Limitation: The 21-gallon capacity may require more frequent dumps on longer trips. Consider upgrading to a larger model if you caravan with a larger unit or multiple helpers.
Camco Rhino 28-Gallon Portable RV Tote Tank
The 28-Gallon model provides a middle ground between compact size and waste capacity, suited for mid-sized RVs or families who travel for longer periods. Its steerable front wheels improve manueverability on uneven terrain, and the built-in gate valve supports straightforward discharge.
- Best for: RVs needing more capacity than a 21-gallon model without the bulk of larger totes.
- Why selected: Steerable front wheels plus a sturdy tow bar simplify transportation across campsites and service roads.
Limitation: It weighs more than smaller units, so it’s best paired with a vehicle or hitch setup that can handle the added weight when full.
Camco Rhino 36-Gallon Portable Camper/RV Tote Tank
With a 36-gallon capacity, this tote is designed for extended trips or larger RVs that require fewer dump stops. It features steerable front wheels and a built-in gate valve, letting owners manage waste with confidence in challenging terrains.
- Best for: RV travelers who prioritize long intervals between dumps and easy steering on rough surfaces.
- Why selected: High capacity reduces frequent trips to the dump station; sturdy HDPE construction resists sun damage.
Caution: The larger size means more space is needed for storage; ensure your cargo area can accommodate the unit when not in use.
Gedlex Bumper Mounted Tote Tank Carrier
This carrier is designed to fit a range of tote sizes (15, 21, 28, and 36 gallons) and supports 4″ or 4-1/2″ bumpers. It’s best for RV owners without ladder configurations who want a modular mounting option and added stability via adjustable bars.
- Best for: RVs lacking ladder access or those wanting flexible tote sizes.
- Why selected: Disassembly and adjustable bars improve storage and stability on the bumper.
Limitation: Not a tote tank itself; it carries the tank and needs compatibility with your bumper and overall RV setup.
Venustank 30 Gallon Portable RV Tote Tank
The Venustank 30-gallon tote is designed for easy maneuverability with two steerable front wheels and large back wheels for stability on various terrains. A 24-inch tow bar enhances towing options behind a vehicle. It’s suitable for users who want a balance of capacity and ease of transport.
- Best for: RV owners who need straightforward towing and stable handling on campsites.
- Why selected: Ready-to-use kit includes everything necessary to move waste from RV to dump station, with maintenance-friendly features.
Limitation: While versatile, verify compatibility with your existing hitch and bumper setup before purchase to ensure a smooth fit.
Buying Guide: Portable RV Waste Tanks
What size should I choose?
Capacity is the primary consideration. Smaller units (around 21 gallons) are easier to store and tow but require more frequent dumps. Larger totes (28–36 gallons) minimize trips at the campground but need more cargo space and higher initial weight when full.
Which wheel design is best for my campsite?
Two main options exist: fixed wheels and steerable wheels. Steerable front wheels offer better maneuverability over uneven ground and through tight spaces, making them ideal for rough campsites. Non-steerable wheels are fine on smooth park roads but can be harder to steer when fully loaded.
What about fit and compatibility?
Look for models with safety-tested materials like UV-stabilized HDPE that resist sun damage. Check bumper or hitch compatibility when using a carrier like Gedlex. Gate valves and large discharge ports reduce mess and time spent dumping.
How important are accessories?
Accessory kits, hoses, and tow bars streamline disposal. Some models include tanks with integrated gauges or indicators to help monitor fill levels. A retainer strap or hose keeper can prevent hose kinks and leaks during transportation.
Durability and maintenance considerations
Durable construction and corrosion-resistant hardware extend the life of portable tanks. Consider models with simple cleaning ports and interior finishes that resist residue buildup. UV resistance helps the unit last longer in sun-baked campgrounds.
