4.)Cassette toilet- my personal opinion is that in some instances it is slightly better than a black tank, but with a blank tank you at least don't have to watch **** flow out, and that smell? It's horrendous, with all the methane and stuff I don't think you will be wheeling your cassette poop suitcase into a mcdonalds or friends house to empty
We had a cassette toilet in our 2006 Northstar Arrow and when used properly with the recommended product for odor there is none. Handling a cassette is easier that using a black hose, rinsing your black tank and the dump station.
