Barker (30844) 4-Wheeler Tote Tank – 42 Gallon capacity
This heavy-duty 42-gallon Barker 4-wheeler tote stands out for its reinforced double wheels and front-swivel design, making it much easier to pull around compared to smaller, two-wheeled options like the SmartTote2. Its large capacity is ideal for frequent or extended trips, but the increased weight can make it cumbersome for those with limited strength or smaller storage spaces. Compared to the Camco Rhino 36-Gallon, it offers better maneuverability at the expense of potentially higher weight and bulk. The rugged wheels and sturdy build mean fewer worries about durability, yet the size limits portability for users with tight storage. This model makes the most sense for campers who prioritize capacity and ease of movement over compact storage.
Pros:- Large 42-gallon capacity reduces frequent emptying
- Double-wheel, front-swivel design for smooth handling
- Heavy-duty build with quiet operation
Cons:- Heavy weight can be difficult to move for some users
- Bulkier size may limit storage options
Best for: Campers needing high capacity and effortless maneuvering, especially with larger or heavier setups.
Not ideal for: Travelers with limited storage space or those who prefer lightweight, easily stowed tanks.
- Capacity:42 gallons
- Material:Polypropylene
- Weight:Approximately 4.79 kg
- Wheel Type:Double swivel wheels
- Dimensions:Not specified

Bottom line: Ideal for users who prioritize capacity and ease of movement over portability and size constraints.
SmartTote2 Portable RV Waste Tote Tank – 2 Wheels – 12 Gallon – Thetford 40505
The SmartTote2 excels in portability, with its lightweight design and fully assembled construction making it perfect for quick trips or limited storage. Its 12-gallon capacity is significantly smaller than the Camco Rhino 36-Gallon, which means more frequent emptying but easier handling for users with less strength or space. Its self-contained hose handling system with AutoStop fill shutoff minimizes spills, unlike traditional tanks that require manual control. However, the smaller size might not suit those with larger waste needs, and the two-wheel design offers less stability on uneven terrain compared to four-wheel models. This pick makes the most sense for RV owners who prioritize simplicity and compact storage for occasional use.
Pros:- Lightweight and compact for easy transport
- Fully assembled with integrated hose handling
- AutoStop fill gauge prevents overflows
Cons:- Limited 12-gallon capacity requires frequent emptying
- Less stable on rough terrain due to only 2 wheels
Best for: Casual RV travelers or those with limited storage who need quick, straightforward waste disposal.
Not ideal for: Full-time RVers or large groups who generate more waste and need bigger tanks.
- Capacity:12 gallons
- Number of wheels:2
- Material:Polypropylene
- Dimensions:30 x 18-1/8 x 10-1/2 inches
- Weight:Lightweight
- Includes:Hose and vent caps
- Fit Type:Universal

Bottom line: Great for infrequent travelers or those with tight storage who want hassle-free handling and sanitation.
Camco Rhino 36-Gallon RV Tote Tank – Features Large Heavy-Duty No-Flat Wheels & Built-in Gate Valve – Removable Steel Tow Adapter, 3’ Sewer Hose & More RV Accessories (39006)
This Camco Rhino 36-Gallon tank is a standout for its rugged, UV-stabilized construction and large no-flat wheels, making it suitable for difficult terrains unlike smaller, plastic tanks. Its size strikes a good balance for those who need significant capacity without the bulk of larger models like Barker’s 42-gallon. The included accessories, such as a 3’ sewer hose and steel tow adapter, make it ready for immediate use, but the 45 lb weight makes it less ideal for users with limited strength or those who need to frequently move the tank.

The Camco Rhino 21-Gallon bundle offers a versatile size for those who want a manageable tank with useful features like a universal gauge to prevent overfilling, unlike the smaller SmartTote2. Its size strikes a middle ground, making it suitable for moderate trips, but it still requires more frequent emptying compared to larger models like the Rhino 36-Gallon. The included accessories, such as the hose and gauge, add value, but the weight and size may still challenge some users for storage and handling. Compared with the 28-gallon tank, this provides a slightly larger capacity with added monitoring, though it’s not as rugged as the larger Rhino. It’s best for those seeking a good balance of size, features, and ease of use.

Camco 3-Foot Super Heavy-Duty Tote Tank Sewer Hose Kit | 18mil HTS Vinyl (39645), Black
This sewer hose kit stands out for its heavy-duty construction and clear elbow, making it easier to monitor tank levels compared to standard hoses. Unlike the typical hoses included with many portable tanks, this kit’s durability minimizes kinks and leaks, especially on rough terrain. Its compact design, extending to 3 feet and compressing to 20 inches, simplifies storage without sacrificing durability. However, the 3-foot length might be limiting for some setups, requiring additional hoses for extended reach. The clear elbow provides visual confirmation of tank status, reducing guesswork during waste disposal. Compared to lighter, less durable options, this kit offers peace of mind for frequent travelers, though it’s a bit heavier and more expensive. This makes it ideal for RV owners prioritizing a secure connection with visible flow, but less so for those seeking ultra-lightweight solutions.
Pros:- Super heavy-duty 18mil HTS vinyl construction resists kinking and leaks
- Clear elbow allows for visual confirmation of tank emptiness
- Swivel fittings enhance ease of connection and sealing
Cons:- Limited to 3 feet length, may require additional hoses for longer setups
- Slightly heavier and more expensive than basic hoses
Best for: RV owners who want a durable, easy-to-monitor sewer connection for frequent use
Not ideal for: Casual campers with occasional needs, as the heavy-duty design adds cost and weight
- Material:18mil HTS vinyl
- Length:3 feet extended, compresses to 20 inches
- Compatibility:Connects to lug sewer fittings

- Fittings:Swivel bayonet ends

Universal Tow Strap for RV Portable Waste Tanks, Towing Bracket for Portable Waste Transport, 15-3/4″Tote Tank Tow Adapter
This tow strap makes hauling your portable waste tank much easier, especially compared to bulky metal bars like the one that came with some tanks. Its strong polyester material and stainless steel hardware ensure long-lasting durability, even on rough gravel roads. The simplicity of wrapping the strap around the handle and connecting to a ball hitch makes it accessible for most users, saving time and effort. Unlike rigid tow bars, this flexible strap minimizes bulk and storage space, making it a practical addition for frequent travelers. Its main tradeoff is that, while sturdy, it might not handle extremely heavy or awkward tanks as securely as metal towing systems. Compared to traditional metal tow bars, this strap offers a lighter, more portable solution with reliable strength for moderate towing tasks. It’s ideal for RV owners who need a lightweight, easy-to-use towing accessory, but not for those hauling very large or heavy tanks regularly.
Pros:- Strong polyester construction resists wear and tear
- Easy to wrap around tank handles and connect to hitches
- Compact, lightweight, and space-saving design
Cons:- May not be suitable for very heavy or large tanks
- Less rigid than metal tow bars, potentially less secure under high stress

The 21-gallon capacity balances size with manageability, although its weight and bulk might be cumbersome for those with limited storage space or weaker handles. The low drain hole facilitates thorough emptying, and the smooth interior makes cleaning straightforward. Compared to smaller tanks with less robust wheels, this model prioritizes durability and ease of movement but at the cost of increased size and weight.
