In the 5 years that we have owned our TT, I have only used the water tank once. I will not tow 90 gallons of water (720 lbs of extra weight) from my house just for the sake of having water I feel comfortable with.
As I read it the OP wasn't asking about the various aspects of towing with a tank full of water brought from home but rather who doesn't hook up to an on-site city water feed and instead continues to draw from their tank, refilling the tank during their stay as necessary. I'm one who does, for the reasons I mentioned.
