Would you "do" a cassette toilet?

I would use a Thetford Curve porta potti.It saves space,has the same tank size as the cassette and is not dependant upon the rigs water supply since it has its own tank.It's well under half the price of the cassette toilet setup and takes nothing to install except a good strapping spot so it won't move during driving.It too can be dumped into any pit toilet,regular toilet or dump station.You should use chemicals that are not harmful to the good bugs in the septic or pit toilet systems.

We dry camp or boondock almost 100% of the time and our cassette toilet allows us greater flexibility when out camping for long periods of no services. For the two of us if careful with the amount of water we use for flushing, 5 days before you have to empty the cassette is not that far fetched. Pit toilets, regular toilets, RV dump stations are just some of the options for dumping. When there is a line up at a dump station, while an RVer is stowing their sewer hose, you bring the cassette over, remove screw cap, direct discharge pipe into sewer intake, press the air release button and in 10 seconds, your black water is finito. The whole process takes 2 minutes from start to finish.

I really wish that when the subject of toilets or black tanks comes up, that those with the idea to******in a bucket or trash bag would just keep quiet. It ALWAYS comes up. We get it - it's a cheap solution. But it's disgusting and fraught with potential problems.

The original question was about cassette toilets. If you can't address the question, then don't post.

There is an inexpensive option that you might consider. There are toilet seats available that snap on top of a 5 gallon bucket, just the right hight as a toilet. These use plastic bags and pouches that are disposable. It sounds a little gross but in reality it is probably more sanitary than emptying a cassette or black tank and you don't need a dump station, just a trash receptacle. We had one in a conversion van once and years ago in a travel trailer when our children were young and they worked out fine when there were no rest rooms available or at night. If you're boon docking without neighbors, you can just use it outside.

I don't have a class B, but a Truck Camper - but with a cassette toilet.

Doesn't the cassette itself, or the compartment get "gross" and need cleaning out?

I can see how it could be handy, but need servicing every 3 or 4 days.

If you rinse the cassette with clear water after use, it stays pretty clean. 2 times are usually enough and all that comes out is clear water. The compartment itself doesn't need a lot of attention. It is a good idea to wipe it clean once in a while, but it doesn't accumulate a lot of gross-ness quickly.

Typically, you need to dump about every 2 days if you are travelling as a couple.

There is an issue with the cassette in that it likes to sputter a little when you use it after you have changed altitude (pressure difference).

Here in Europe, many people have installed an SOG kit (link below). The kit contains a small fan that engages as soon as you move the flush lever. It vents all gases in the cassette to the outside through a carbon filter. Not only does it eliminate any sputtering - it also lets you use the cassette without any chemistry / deodorant. So you can dump the contents into any toilet along the way.

Dumping itself is straightforward and just as clean (or dirty) as with a black tank - but minus any hassles with a dump hose.

I wouldn't want to go back to the black tank system. But I would like to carry a spare cassette (for which I have no space in my truck or camper).

I had one (portable)that saved the day when my toilet drain pipe and base mount had a problem. Removed the toilet and set the cassette on two 2x4's right over the drain hole for three days waiting for a mobile repairman. Worked fine, Emptied it right down the drain. Very doable.

Allows you to have a toilet without the need for a black tank. If the chassis layout allowed room for a larger black tank that would be the way to go IMO. If not, then a cassette toilet is preferable to none. We had one in the pop-up years ago and the cassette comes out like a mini portable black tank that you take up to the dump station.
