I thought that also but in NZ last year I rented a Sprinter camper van with a Thetford cassette toilet. Wasn't too thrilled when I saw that in the specs but it turned out to be great and with one qualification, I'd prefer it over the black water tank. It's so easy to use. If there's numerous dumps it's so simple to pull out the casette and walk over to the dump site, no hooking up required. The only reservation I had is if the sealing mechanism failed it could be quite a problem. It worked well for the two weeks that I had it but long term could be an issue.
