How to winterise a caravan stored outdoors

A caravan can be stored outdoors over winter, but not on grass or damp ground, as this can promote corrosion. Before storage, the interior should be thoroughly cleaned, and mothballs or fabric softener sheets used to deter rodents. All tanks must be drained and filled with non-toxic RV antifreeze. Propane cylinders should be closed, and the battery connected to a smart charger in a dry, temperate location. Sealants should be inspected and appropriate caulk used to prevent water ingress. Dealers often offer this service at a flat rate.
