Buying Guide
What size tote should I get?
Capacity ranges from about 10–36+ gallons. Choose based on how far you are from dump stations, how often you plan to empty, and your RV’s number of occupants. Larger totes reduce trips but are heavier to move.
Are wheels and towing important?
Yes. Look for no-flat wheels and a stout tow adapter if you plan to tow behind a vehicle or roll across uneven sites. Front steerable wheels help with turning and stability on rough ground.
What about durability and materials?
Most tanks rely on UV-stabilized HDPE or PP. Durable construction resists sun damage and outdoor elements. Check for reinforced handles and leak-free gate valves to prevent spills.
How easy is emptying and cleaning?
Large ports, smooth interior surfaces, and built-in tank rinser features improve cleanup. Models with clear indicators or simple drain setups speed up routine maintenance.
Is there a good all-around choice?
For a balance of capacity, mobility, and ease of use, consider the 36-gallon options from Camco or RecPro. For smaller spaces, a 21–30 gallon tote with sturdy wheels and a tow adapter is often best.
Important considerations by scenario
- Snowbird or long-term sites: prioritize high capacity and reliable wheels.
- Family trips with frequent dumps: a mid-to-high capacity model with easy draining helps.
- Small RVs and tight storage: compact totes with long handles and easy rollout are ideal.
Frequently Asked Questions
- Can I use a portable waste tank for both black water and gray water? Answer: Some models are designed for black water, while others accommodate both. Consult product specs to confirm the intended use.
