Bailey Olympus Locker Doors

We have an early (2010) Bailey Olympus 534.  The overhead locker doors have a plastic catch at the bottom which is supposed to engage with a plastic strip on the bottom of the locker.  During autumn 2010, I found that some of the catches were not engaging and asked the dealer to rectify.  The dealer adjusted the hinges but the problem recurred the following autumn so I contacted Bailey who, again said it was just a matter of hinge adjustment.  Over time it has become clear that the curvature of the doors reduces in colder and/or damper weather so that doors latch closed in the summer but fail to do so when the weather cools.  I note that more recent versions ofg our 'van have different doors and catches which suggests Bailey recognised a problem and I have written to the company.  Has anyone else experienced this problem?
