A common toilet uses 1.6 gallons, a black tank holds let say 40 gallons. That gives you about 25 flushes before you need to dump. 25 flushes for two people would be every day or two for dumping.
Now if you left the valve open you would get the pyramid of poo in no time at all.
Proven solution to prevent this:
With one person, keep the shutter-valve on the drain pipe closed and only open it every other day (and then close it again for 2-3 days).
With 2 people open it once a day - say, in the morning.
Needless to remind to always add some water or liquid waste before using it again after emptying.
RV toilet with all-porcelain bowl with a proper swirl-flushing like Dometic 310/320 would be my preferred solution when water supply is limited.
