33gal freshwater, about how long will it last?

Some could make it last 2 or 3 days, others can go through it with one shower.
Do you take military showers?
Do you let the water run when brushing your teeth?
Do you let the water run when you wash your hands?
Do you let the water run when you do dishes?
Do you use the campground showers?
Do you use the campground bathroom?

You get the idea lots of variables.
