Just bought my "new to me" 320 and can't find the holding tank capacity anywhere in the manual. I have read online everything from 20 to 40 gallons. Either way, my concern is that 40 gallons of fresh water empties a lot quicker than the holding tank fills. If I understand the system correctly this is because the gray water (shower and A/C drain) all pump overboard? Is that the correct understanding? And before anyone asks, yes, the macerator seacock is closed.
