Not everyone enjoys using their caravan in the winter months, so many mothball their caravans for the winter. If done well a caravan can emerge from its winter hibernation in good condition and be ready to use again with only a few hours work.
Make sure that your caravan is spotlessly clean before closing it up for the winter. The shower, toilet, oven and fridge, in particular, need to be thoroughly cleaned and wiped dry. To avoid mould in the fridge, prop the door open. Drain all water from your caravan to avoid frost damage. Turn off the gas to all appliances.
Even people who have space outside their house sometimes put their caravans into storage during the winter. Choose the company that you use for this carefully. Find one that will pick up your caravan and bring it back to you, that way you can use companies from further afield and get a better choice of companies. Some companies will get your caravan serviced for you whilst they take care of it. They may also offer a repair service, which can be useful.
Try to find a company that will keep your caravan indoors. It will be completely protected from the elements and it is more secure.
If you cannot find indoor facilities, choose your outside storage company carefully. Use a company who takes security seriously. At the very least, they should have on site security or CCTV. Because your caravan will be exposed to the elements, it is important to periodically check your caravan for leaks. Make sure that the company you use, allows this. Do not leave anything of value in your caravan; even with security, stored caravans still get broken into.
Where ever you choose to store your caravan use this period of inactivity to get your caravan serviced, repaired or updated. Ensure that the bodywork and roof are checked for any cracks, which in the winter can turn into leaks that will seriously damage your caravan.
