Best for heavy RV use and longer travel days, the Camco Rhino 36-Gallon Tote Tank offers large capacity and rugged mobility. Its no-flat wheels and oversized handle support transport across uneven surfaces, while the steel tow adapter enables towing behind a truck or golf cart. At 45 lb, it is sturdy enough for frequent dump runs yet manageable for a single person. This model suits full-timers, and campers who regularly park far from dump stations.

Selected for: longest single-haul capability and durable HDPE construction that withstands outdoor exposure. Best avoided if you need ultra-lightweight gear for occasional trips, or if space is severely limited in your storage bay.

Data cues from features: 36 gallons; dimensions around 24 1/8” L x 14 3/4” W x 44 7/8” H; UV-stabilized blow-molded HDPE; built-in gate valve and tow adapter enhance dump-site compatibility. Its heavier weight improves stability but can complicate handling for users with limited strength or space.

This is a practical choice for weekend warriors or mid-length trips where dump points are not immediately nearby.

Selected for: a balance of storage and maneuverability. Choose this if you need more capacity than the smallest model but still require easier handling than a 36-gallon unit.

Data cues from features: 28 gallons; 14 ½” L x 24” W x 44” H; HDPE construction; durable for outdoor use. Limitation: slightly smaller capacity than the 36-gallon version, so fewer dumps between visits to stations.

Buying Guide: Key Considerations For Choosing A Caravan Waste Tank

Capacity and travel pattern: If you undertake long trips away from dump stations, favor larger capacities (30+ gallons). Shorter trips can use smaller models (20–28 gallons) to save weight and space.

Mobility and handling: Look for no-flat tires, a comfortable oversized handle, and a steel tow adapter for easier towing behind vehicles. Consider the total packed weight and storage space in your caravan.

Durability: UV-stabilized HDPE or similar materials resist sun exposure and weather conditions. Heavier models tend to be more stable during transport but are harder to maneuver alone.

Ventilation and venting options: Some models require manual venting or come with a built-in valve system. Ensure you understand how to vent safely during draining to avoid pressure buildup.

Compatibility and installation: Some tanks are plug-and-play, while others demand custom inlet/vent placements. Assess your RV’s existing plumbing and whether you’re comfortable with DIY modifications.

Maintenance and cleanliness: A larger opening or large ports facilitates easier emptying and cleaning. Consider color and interior finish for visibility when cleaning and draining.
