37 gallon gray and black tanks in our TT, and it's just DW & me. We use regular dishes and take daily Navy showers. The black tank will go at least a week, but we'll fill the gray tank (and empty the FW tank) in 2-3 days.
But - I have a 30 gallon drum in the back of the F150 and a 12V pump. Gray water gets pumped & taken to the dump station as needed.
