Hi, We have a 2014 Chausson 510 which has developed cracks around the front skylight recess above the cab. I assume this has had a whack at some time. It was originally repaired by the dealer under warranty but the cracks have now opened again. Does anyone know of a reliable repairer in or around the Sheffield area please ? We have had one quote but £730.00 seems a little steep! Any help would be appreciated. Thanks Ann & Pat.
