Storage

[Flyingscotsman1]

evening all, has anyone any experience of keeping our caravans in storage for this long do fringes water systems and water heaters suffer problems with not using them i have a collection of classic motorcycles with do suffer from mot being used

Shouldn't suffer unduly but without a solar panel to top up the battery won't be much good if the voltage falls too low.
One year I had mould problems through use of a caravan cover.
