Why don't you use your new Bailey during the winter? Modern caravans can be used year-round, you can be warm and snug with your heatint on, and on a lovely site with heated toilet blocks, and never have to 'winter' your van again. All you need do is protect the water system again freezing (bubble wrap your aquaroll) and use Propane instead of Butane. You'll discover a whole new world of winter caravanners.
