We purchased our brand new Lunar Lexon 640 in March this year, we went away in it several weeks over a three month period, after about 12 weeks we noticed the floor was getting quite springy in the kitchen area and by the time we came home it was getting really soft to the point we tried to avoid standing on it. We took it back to the dealer and their workshop said in their opinion it wasn't delamination. They then got in touch with Lunar who sent a so call expert out have a look at the floor, and in his report he said it was simple delamination and it could be repaired by cutting the floor out from underneath, adding extra bearers and then drilling holes inside caravan floor and pumping resin into it. I then told them I didn't want a repair, I wanted a new caravan or a refund as this caravan is not fit for purpose. Lunar now insist they have to be allowed to effect a repair. We are about at our wits end as our caravan was taken into dealers at the beginning of August and up to today still hadn't started the repair, we have missed the whole of the summer holiday period and still no idea when we'll get it back. This was our first Lunar caravan after always having Baileys, but I wish I had never seen a Lunar now.
