From my perspective these are a cassette system key differentiating points versus a black tank or acomposting toilet:
- Cassette is a fully integrated system allowing easier installation and more flexibility in layout (vs a regular gravity based black tank toilet, macerator toilet allows flexibility but it is way more complex),
- Dumping is not restricted to dump stations only,
- Water flush, so it is like a regular toilet, same cleaning as at home,
- Cassette’s plastic bowl is more prone to scratching than an optional ceramic toilet with a black tank, but a ceramic one is heavier,
- Volume of 5 gal. will decrease dumping intervals 3 times versus commonly used 16 gal. black tanks,
- Easy thorough cleaning which is not really possible with a black tank, important for my garage storage,
- For smaller vans cassette’s smaller overall volumes allow easier optimization of all tanks. For example: my sub-20' long van is completely filled below the floor with the 12 gal. fresh water tank, the 4 gal. hot water heater, the 14 gal. grey water tank and above the floor the 5 gal. cassette and 4 gal. flush water. Sacrificing road clearance allows bigger tanks but road clearance for us was an overdriving objective, no skirts.
- Easier for 4 season van including possible use of freeze preventing chemicals in the flush water tank,
- From my personal experience the cassette has on odor, but my Bigfoot truck camper with a black tank had lingering odor, never figured out why but I met others with the same truck campers experience, it could be black tanks locations.
- The biggest controversy about cassette is actual dumping. Certainly not fun, one of the necessary evil. I manage it OK, tend to dump between ½ to ¾ full, pressing on the vent to prevent vacuum generated splashing is critical. It is likely less repulsive than dry cleaning of a composting toilet.
- If you have a large family and volumes of toilet paper are generated by kids go with a black tank,
- If it just for a couple the choice would depend on your dumping frequency desires and actual dumping preference,
- If you often use camping restrooms and van’s toilet is primarily for nights a cassette could be a better choice,
- For small van a cassette system makes more sense.
