Preparing your touring caravan for the winter is essential.
Firstly, and most importantly, drain the water system to prevent sub-zero temperatures from freezing the pipes. Water expands when frozen and can easily split pipes (even metal ones), causing pumps to break internally and damaging water storage tanks, potentially resulting in expensive repairs.
If you intend to leave your caravan unused for long periods, consider disconnecting or removing the battery (unless you have an alarm fitted). Completely draining a leisure battery can cause problems and may result in it no longer being able to hold a charge. Remember, even when not in use, a battery will discharge slowly over time, so keep it topped up by charging it regularly (once every two months or so) and store it in a warm place, not on a concrete floor.
