My mother has a 3 year old Corona 556. At its first service the dealer found damp under the outer locker door. They ordered a new door but it took almost 10 months to arrive & fit. The second annual service (shortly after the new door was fitted) showed 40% damp under that area. She was told it would dry out. She's just had the third service & it's still showing 40% damp. She demanded they fix it but the service manager told her "all caravans are damp at this time of year, bring it back in June". I find this attitude appalling. To me they're just fobbing her off & more damage is being done. She puts her van on a seasonal pitch & relies on others towing it for her so it's not even convenient for her to bring it back in June! So she's thinking of getting an independent engineer in to damp test it in June & if it's no better she's gonna demand it be fixed at the end of the season. Do you think this is wise or should she demand it be fixed right now even though she may miss some time on her site?
