We usually have highs in the 50's and 60's here in north Florida in January and the first part of February, then it goes up from there on. We can have temps into the 20's occasionally and frequently get them in the 30's overnight here. We rarely to never see frozen puddles, so I doubt your lines would freeze. This will be our first winter with our TT, but we do not see a reason to winterize it. Folks from up north camp down here all winter without problems.
