Preparing your touring caravan for the winter is a must. Firstly, and most importantly, drain the water system to prevent the sub-zero temperatures from freezing the pipes. Water expands when frozen and can eaisly split pipes (even metal ones), cause pumps to break internally and wreck water storage tanks leaving you with potentially expensive damage.
If you intend to leave your caravan for long periods, consider disconnecting or removing the battery (unless you have an alarm fitted) draining a leisure battery completely can cause problems and may cause it no longer hold its charge. Remember, even when not in use, a battery will discharge slowly over time, so keep it topped up by charging it regularly (once ever two months or so) and make sure to store it in a warm place, not on a concrete floor. If you must leave the battery in the caravan, remember to isolate it from the 12v appliances, and check its charge often, so its life can be prolonged.
It’s best to visit your caravan every so often to check things over. Open the windows to air it out and check for mould, which will only get worse over time if left. Empty the fridge and dry it completely, leaving the door slightly ajar so it also airs out. Removing the cushions and bedding is also a good idea if possible to prevent them becoming damp with condensation, and can also deter thieves.
