9 Best RV Tote Tanks for Dumping Without Moving the Rig (October 2026)
The best RV tote tanks for portable waste disposal include the Camco Rhino 36-Gallon Tote Tank with Steerable Wheels for steerable large-capacity hauling, the Camco Rhino 36-Gallon Tote Tank for a large, simple wheel layout, and the Camco Rhino 28-Gallon Tote Tank for mid-size capacity.
On this page (5 sections)
The best RV tote tank lets you carry waste to a dump station without moving the rig, and the right size depends on your load, route and storage space. For a large capacity with steerable front wheels, the Camco Rhino 36-Gallon Tote Tank with Steerable Wheels is our top pick.
A tote tank helps when your site is far from a dump point or your sewer hose won't reach. Capacity is only part of the choice: wheel layout, towing hardware, hose inclusions and the space available to store the tank all matter.
If cold weather is part of your setup, see our guide to RV holding tank heaters and keeping RV pipes from freezing at the campsite. Those topics cover freeze protection, while this roundup focuses on moving waste to a dump station.

Which RV tote tank is best for your setup?
The Camco Rhino with steerable wheels is the strongest all-around pick for larger loads, while the Barker 42-gallon model has the highest stated capacity. Smaller options trade capacity for a more compact tank or fewer pounds to move when empty.
Camco Rhino 36-Gallon Tote Tank with Steerable Wheels: Best for steerable large-capacity hauling
- 36-gallon capacity
- Two steerable 6 in front wheels
- Two 12 in heavy-duty wheels
- Includes a 3 ft sewer hose
Steerable front wheels and large rear wheels make this the most maneuverable large Camco option here. It also includes a tank rinser, ladder hook and gate valve.
Pros
- Steerable front wheels
- Large 36-gallon capacity
- Tank rinser and gate valve
Cons
- Largest stated size among the Camco picks
- 55 lb stated weight
The Camco Rhino 36-Gallon Tote Tank with Steerable Wheels pairs a 36-gallon capacity with two steerable 6 in front wheels and two 12 in rear wheels. That layout gives you more directional control than a basic two-wheel tank when maneuvering toward the dump point.
It includes a removable 24 in tow bar, a 3 ft sewer hose, a tank rinser, a ladder hook and a gate valve. The stated weight is 55 lb, so consider where you'll store it and how you'll position it before filling.
Camco describes the tank as UV-stabilized blow-molded HDPE. The wheels are no-flat, and the oversized handle gives you another way to move the empty tank by hand.
Choose this Rhino when steerability and a large capacity both matter. If you need the greatest stated capacity, compare it with the Barker 42-gallon option below.
Camco Rhino 36-Gallon Tote Tank: Best for a large, simple wheel layout
- 36-gallon capacity
- Two oversized no-flat wheels
- Large handle
- Tank rinser and gate valve
This 36-gallon Rhino has two oversized wheels and a large handle. It includes a tank rinser and ladder hook, with a steel tow adapter for towing.
Pros
- 36-gallon capacity
- Two oversized wheels
- Tow adapter included
Cons
- No steerable front wheels
- Check storage clearance against the stated dimensions
This Camco Rhino 36-Gallon Tote Tank offers the same capacity as our top pick, but uses two oversized wheels instead of steerable front wheels. It includes a large handle, steel tow adapter, tank rinser, ladder hook and gate valve.
The included tow adapter is designed for towing behind a truck or golf cart. For hand movement, the large handle and no-flat wheels provide a straightforward two-wheel arrangement.
Its stated dimensions are 24.125 x 14.75 x 44.875 in, so measure the compartment or storage bay where you plan to keep it. Don't rely on the tank capacity alone when checking fit.
Pick this one if you want a 36-gallon Rhino with a simpler wheel layout. The steerable version makes more sense if front-wheel direction control matters on your route.
Camco Rhino 28-Gallon Tote Tank: Best for mid-size capacity
- 28-gallon capacity
- Two oversized no-flat wheels
- Large handle
- Tank rinser and gate valve
The 28-gallon Rhino keeps the same basic two-wheel layout and tank rinser as the larger option. Its lower capacity may suit a smaller waste load.
Pros
- Middle capacity among the Camco tanks
- No-flat wheels
- Steel tow adapter included
Cons
- No steerable front wheels
- 43 lb stated weight
The Camco Rhino 28-Gallon Tote Tank reduces capacity from 36 gallons while keeping the oversized two-wheel layout. Its large handle, tank rinser, ladder hook and gate valve cover the main handling and cleanup features.
Camco includes a steel tow adapter, a 3 ft sewer hose and additional fittings. The tank is made from UV-stabilized blow-molded HDPE, and its stated empty weight is 43 lb.
This mid-size capacity can suit RVers who have less waste to move per trip or prefer not to store a 36-gallon tank. The listed dimensions are 14.5 x 24 x 44 in, so check both the height and the available floor space.
Choose it for a conventional two-wheel Rhino in a middle capacity. If you want steerable front wheels, compare the next Camco model.
Camco Rhino 28-Gallon Tote Tank with Steerable Wheels: Best for steering with mid-size capacity
- 28-gallon capacity
- Two steerable 6 in front wheels
- Two 12 in rear wheels
- Includes a 3 ft sewer hose
Steerable front wheels distinguish this 28-gallon Rhino from the standard two-wheel model. It includes a tank rinser, ladder hook and gate valve.
Pros
- Steerable front wheels
- 28-gallon capacity
- Several hose and rinse accessories included
Cons
- 53 lb stated weight
- Compare the tall profile with available storage
The Camco Rhino 28-Gallon Tote Tank with Steerable Wheels combines a mid-size capacity with the same steerable front-wheel arrangement as the 36-gallon steerable model. Its two 6 in front wheels turn, and two 12 in rear wheels support the tank.
The kit includes a 3 ft sewer hose with swivel fittings, rinse adapters, clear elbows, storage caps and a steel tow adapter. A built-in tank rinser and gate valve support emptying and cleanup.
At 53 lb stated weight, this version is not the lightest 28-gallon choice. The 24.5 x 13 x 44 in dimensions are useful when comparing storage, but allow room to remove and attach the tow bar.
Choose this model when you want steerable wheels but don't need 36 gallons. For a simpler wheel setup and lower stated weight, the standard 28-gallon Rhino is the alternative.
Camco Rhino 21-Gallon Tote Tank: Best for smaller waste loads
- 21-gallon capacity
- Two oversized wheels
- Tank rinser
- Ladder hook
The 21-gallon Rhino is the smallest Camco capacity in this roundup. Its kit includes a 3 ft sewer hose and a steel tow adapter.
Pros
- Smallest Camco capacity here
- Tank rinser and ladder hook
- Tow adapter included
Cons
- Less capacity between dump trips
- No gate valve is specified in its listed features
The Camco Rhino 21-Gallon Tote Tank is the smallest capacity Camco pick here. It includes two oversized wheels, a handle, tank rinser and ladder hook, plus a 3 ft sewer hose and steel tow adapter.
Its stated weight is 34.5 lb, lower than the other Camco tanks in this roundup. That can matter when moving it empty, though a filled tank still needs a suitable route and handling plan.
The 21-gallon size may fit smaller waste loads and tighter storage spaces. Check the listed dimensions of 20.125 x 12.5 x 40 in against your compartment before deciding.
Choose it when a large tank would be hard to store or manage. If you need to go longer between trips to the dump station, compare the 28- and 36-gallon models.
Barker 4-Wheeler 42-Gallon Tote Tank: Best for maximum listed capacity
- 42-gallon capacity
- Four wheels with a front swivel pair
- 3 in waste valve
- Includes a 5 ft sewer hose
Barker's 42-gallon tote offers the largest stated capacity here, with a low profile and double front swivel wheels. Its 3 in waste valve is designed for dumping without lifting the tank.
Pros
- Largest stated capacity here
- Four-wheel layout with front swivels
- Includes a 5 ft sewer hose
Cons
- 47 lb empty weight
- Confirm the low profile fits your storage plan
The Barker 4-Wheeler 42-Gallon Tote Tank has the largest stated capacity in this roundup. Its four-wheel layout uses double swivel wheels at the front, and its 3 in conventional waste valve is designed to let you empty it without lifting the tank.
The tank is made from blow-molded polyethylene, zinc-plated steel and aluminum. It includes bayonet fittings, a 5 ft sewer hose and a tow handle, with a stated empty weight of 47 lb.
Its low profile measures 46 x 24 x 14 in. That shape can fit storage spaces where height is limited, but its length and width still need careful measuring.
Pick the Barker when capacity is the main priority and you have room for its footprint. A 32-gallon Barker keeps the four-wheel layout in a shorter height.
Barker 4-Wheeler 32-Gallon Tote Tank: Best for a low-profile four-wheel tank
- 32-gallon capacity
- Four wheels with a front swivel pair
- 3 in waste valve
- Includes a 5 ft sewer hose
This Barker keeps the four-wheel layout and 3 in waste valve while offering less capacity than its 42-gallon sibling. Its 11.5 in stated height can help when vertical storage room is limited.
Pros
- Low stated height
- Front swivel wheels
- Includes a 5 ft sewer hose
Cons
- 40.4 lb stated weight
- Check length and width before storage
The Barker 4-Wheeler 32-Gallon Tote Tank offers less capacity than the 42-gallon version, with the same front swivel wheel design and 3 in waste valve. Its stated height is 11.5 in, the lowest among the tanks here.
Barker includes bayonet fittings, a 5 ft sewer hose and a tow handle. The tank's materials are blow-molded polyethylene, zinc-plated steel and aluminum, and its stated empty weight is 40.4 lb.
The 45 x 24 in footprint still takes substantial floor space even with its low height. Measure the full storage area and consider how you'll get the tank back out when needed.
Choose this model if you want four wheels and a low tank profile. For more capacity in the same general style, the 42-gallon option is the next step.
Thetford SmartTote2 12-Gallon Tote Tank: Best for compact, light loads
- 12-gallon capacity
- Two wheels
- Compact stated dimensions
- Caps for hose opening and vent
The compact SmartTote2 is a better fit for small waste loads or limited storage than a large-capacity tank. It comes assembled with caps, but a hose is not included.
Pros
- Compact stated dimensions
- Fully assembled
- Caps for hose opening and vent
Cons
- Smallest capacity here
- Hose not included
The Thetford SmartTote2 12-Gallon Tote Tank is the most compact capacity choice here. It comes fully assembled with caps for the hose opening and vent, and its stated dimensions are 31.5 x 11.3 x 18 in.
This two-wheel tank is described as lightweight and easy to store. A hose is not included, so plan for compatible hose and fittings before a dumping trip.
At 12 gallons, it suits small loads or RVers who can make more frequent trips to a dump point. It isn't the right choice if you want to move a large holding-tank load at once.
Pick it for compact storage and modest capacity. If you want a middle capacity with a tow bar and hose included, consider the Venustank below.
Venustank 30-Gallon 2-Wheel Tote Tank: Best for a mid-capacity kit
- 30-gallon capacity
- Two large solid-rubber back wheels
- 22 in tow bar
- Includes a 3 ft sewer hose
Venustank's 30-gallon option includes a tow bar, sewer hose, rinse adapters and other accessories. Some assembly is required.
Pros
- 30-gallon capacity
- Tow bar and cleaning accessories included
- Large solid-rubber back wheels
Cons
- 57.5 lb stated weight
- Some assembly required
The Venustank 30-Gallon 2-Wheel Tote Tank sits between the smaller Camco and larger 36-gallon options in capacity. It has two large solid-rubber back wheels and a 22 in tow bar that lets you roll it by hand or tow it behind a truck or golf cart.
The kit includes a 3 ft sewer hose, rinse adapters, elbows, caps and the tow bar. It also has gate valves, a smooth interior, an integrated tank rinser and a ladder hook.
Its stated size is 43.5 x 25.5 x 17 in, and it weighs 57.5 lb. Some assembly is required, so allow time to put it together before your first use.
Choose this tank if a 30-gallon capacity and included accessories fit your needs. The Camco 28-gallon models are alternatives if you prefer either a standard or steerable wheel arrangement.
How do you choose an RV tote tank capacity?
Choose a tank that can carry the amount of waste you expect between dump trips, while leaving room to store and move it. A larger tank means fewer trips, but capacity does not remove the need to check weight, dimensions and route.
The biggest option here holds 42 gallons, while the smallest holds 12 gallons. Think about your RV's holding-tank capacity and how full you expect it to be before making a choice.
An RV tote tank can become heavy when full. Avoid filling it beyond what you can safely maneuver, and follow the tank instructions for filling, towing and dumping.
Do wheels and tow bars matter on a full tank?
Yes, wheel layout and tow hardware affect how you move a loaded tank. Swivel or steerable front wheels help with direction changes, while a tow bar or adapter gives you a defined attachment point.
The Camco steerable models use two small front wheels and two large rear wheels. Barker's 4-Wheeler tanks use a front swivel pair and two additional wheels, while the Thetford SmartTote2 uses two wheels.
Check the path from your RV to the dump station before buying. Loose ground, slopes, tight turns and thresholds can all affect how manageable a filled tank is.
What should you check before storing a tote tank?
Measure the full storage space and compare it with the tank's dimensions, including room for handles or tow bars. Also check whether the hose and fittings have a place to stay clean and secure.
A ladder hook appears on several Camco models, and the Thetford includes caps for its hose opening and vent. If your winter setup also needs protection for water lines, see our guide to heated water hoses for RVs and heated water lines.
Follow the tank maker's instructions for rinsing and storing it after use. Keep waste hoses and fittings separate from drinking-water equipment.
Which RV tote tank should you choose?
Pick the Camco Rhino 36-Gallon Tote Tank with Steerable Wheels if you want a large capacity with steerable front wheels. Choose the Barker 42-gallon model if maximum capacity is the priority, the 21-gallon Rhino for smaller loads, or the Thetford when compact storage matters most.
Before buying, compare tank dimensions with your storage bay and consider the route you'll roll it on. For more cold-weather planning, read our winter RV skirting guide.

Frequently asked questions
What size RV tote tank should I get?
Choose capacity based on how much waste you need to move and how often you can reach a dump station. A 12- or 21-gallon tank suits smaller loads, while 28 to 42 gallons gives more room between trips.
Also check the tank's dimensions, since a larger capacity can take more storage space.
Can I tow an RV tote tank behind a vehicle?
Some portable tanks include a tow adapter or tow bar for towing behind a truck or golf cart. Check the specific tank's instructions and use its intended attachment.
Plan the route around the tank's wheel layout, ground conditions and the distance to the dump station.
How do you choose between two and four wheels?
A two-wheel tank may store more compactly, while a four-wheel tank can stay upright as you roll it. Steerable or swivel front wheels can help with turns.
Compare the wheel setup with your route and storage space, since a narrow path or uneven ground can change which layout feels manageable.
Does every RV tote tank include a hose?
No. The Thetford SmartTote2 12-gallon tank does not include a hose, while several other picks here include a 3 ft or 5 ft sewer hose.
Check the included fittings and hose length against your RV outlet and dumping setup before you buy.
Can I use a tote tank for gray water?
Portable waste tanks can move RV waste to a dump station, but confirm that the tank and your campground allow the intended use. Follow local disposal rules and the tank's instructions.
Keep hoses and fittings clean, and don't use waste handling equipment for drinking water.
