For several weeks now we have been able to open and close our rooflights but not lock them. When the rooflight reached it's closed position it was possible to continue turning the handle (click, click, click) but the rooflight wouldn't lock. We rang Spinney, they explained that Autotrail had a problem with the gear box mechanisms, did we want to bring the motorhome in or do it ourselves, simple job they said. Well all three of them arrived today via UPS including new handles (well done indeed Spinney) and forty five mins later all done and working good as new. They didn't tell fibs, they really are that easy to do. Anybody else had similar problems?
