I'm not sure that anyone's suggested "to watch the weather and use a little common sense".
Around ATL- I'd think most of the time (Early and Late winter) your camping trips would have minimal freeze risk- I'd use the holding tanks at will (dump them at the end of the trip), and your call on whether to use the water system...
(Of course, if the weather man is predicting an unseasonable hard freeze, you operate more cautiously)
Then, maybe for December and January-where a hard freeze is more likely, have the unit fully winterized and maybe don't even use the holding tanks....
I definitely would NOT take the camper to storage without the lines being blown out.
There can be some fierce debates over JUST blowing and no anti-freeze...Just blowing is not perfectly safe (there's usually one poster who will chime in with a busted pipe story). That one person is countered with generally-overly-confident folks spouting how they've just blown for 10-zillion years and never had a problem...
To me, re-winterizing after EVERY trip would be a pain- but by watching the weather and maybe roughing it more in the heat of winter would help you not have to re-winterize.
There's a risk- a small one- but it's your call, not ours.
Definitely go for it- we have had some wonderful 'wintertime' camps including several with hard, overnight freezes.
