Ok so when we put our caravan away in October it was fine-been to check everything today-all good-battery fine, legs go up and down, locks not rusted on-we're good to go-washed and polished. Went inside and did a stock take but now none of the doors with soft closers on them will close-the closer is too firm-popped some silicone lube on and got them shut , but any ideas anyone?
