As you are probably aware, I am a complete newbie to the motorhome life. So I have a question - how do you use the toilet? This may seem strange to the experts, but having never used a chemical toilet I really do not know how it works. Do you just do what you need to do and flush? Taking into account the limited amount of water you have and the limited capacity of the cassette, I can imagine this is not the case. So please enlighten me.
