The Camco Rhino Portable RV Waste Holding Tank is a solid choice for RV owners needing to transport waste to dump stations. With a 36-gallon capacity, it’s designed to handle the waste needs of most RVs and trailers. One of its key strengths is its ease of transport; the large, no-flat wheels and removable steel tow adapter allow for smooth movement, whether you're pulling it behind a vehicle or rolling it like a suitcase. Its construction from high-density polyethylene (HDPE) ensures durability and resistance to punctures, which is essential for this type of product.

Although it is portable, lifting it may still pose a challenge for those with limited strength. Additionally, even though the included accessories are beneficial, some users may find they need additional parts for specific setups, which could lead to extra expenses.

The Camco Rhino 28-Gallon RV Tote Tank is designed to make waste disposal easier for RV users, especially when the campsite's dump station is too far for your RV’s sewer hose.

This tote tank represents a reliable, portable waste solution combining durability, ease of movement, and helpful accessories for RV owners.

Buying Guide for the Best Portable Rv Septic Tank

Choosing the right portable RV septic tank is crucial for ensuring a hassle-free and comfortable camping experience. A good septic tank will help you manage waste efficiently and keep your RV clean and odor-free. When selecting a portable RV septic tank, consider factors such as capacity, material, ease of use, and portability. Understanding these key specifications will help you make an informed decision that best suits your needs.
CapacityCapacity refers to the amount of waste the septic tank can hold, usually measured in gallons. This is important because it determines how often you will need to empty the tank. Smaller tanks (5-10 gallons) are easier to handle and transport but require more frequent emptying, making them suitable for short trips or solo travelers. Medium tanks (10-20 gallons) offer a balance between capacity and portability, ideal for small families or weekend trips. Larger tanks (20+ gallons) can hold more waste, reducing the frequency of emptying, which is beneficial for longer trips or larger groups. Choose a capacity that matches the duration of your trips and the number of people using the RV.
MaterialThe material of the septic tank affects its durability and weight. Common materials include polyethylene, polypropylene, and ABS plastic. Polyethylene is lightweight and resistant to chemicals, making it a popular choice. Polypropylene is also durable and resistant to cracking. ABS plastic is known for its strength and rigidity. When choosing a material, consider the conditions in which you will be using the tank. If you need a lightweight option for easy transport, polyethylene might be best. For more rugged use, consider polypropylene or ABS plastic for their durability.
Ease of UseEase of use encompasses features that make the septic tank simple to operate and maintain. Look for tanks with large, easy-to-access openings for filling and emptying, as well as clear indicators for waste levels. Some tanks come with built-in handles or wheels for easier transport. Consider how easy it is to clean the tank, as regular maintenance is essential for preventing odors and ensuring longevity. Choose a tank with user-friendly features that match your comfort level and physical capabilities.
PortabilityPortability is a key factor, especially if you plan to move the tank frequently. Features that enhance portability include wheels, handles, and compact design. Tanks with wheels are easier to maneuver, especially when full. Handles should be sturdy and comfortable to grip. A compact design ensures the tank can be stored easily when not in use. If you plan to travel often or have limited storage space, prioritize portability to make handling the tank more convenient.
Connection CompatibilityConnection compatibility refers to how well the septic tank connects to your RV's waste system. Ensure the tank has compatible fittings and adapters for a secure and leak-free connection. Some tanks come with universal fittings, while others may require specific adapters. Check your RV's waste system specifications and choose a tank that matches or includes the necessary adapters. This will ensure a smooth and efficient transfer of waste, preventing spills and leaks.
