Hi Folks, just an update on where we have got to with everything. Ive been in touch with the seller and explained the situation, he has also seen the photograph. He was very nice and said he had no idea and apologised. He said that if the floor is as we have said it is then he will give us a full refund and asked if we still have the carpet for it. When I explained the carpet is now in pieces and can no longer be put back down and also that we have started to paint the interior he said that he wouldn't be able to accept it back as it is not in the same condition as when he sold it and that customers dont want a painted caravan and so it would be no good to him. I do understand his point, as I imagine he planned to fix the floor and put it straight back on the market again. I explained to him that I did understand, but we would never have started the work if we had known about the floor problem. He said to take it back to him and he will get the engineer to look at it to see the extent of the damage. We are returning it next week and in the meantime have got an approved technician coming out this week to give us a report to assess the problem, who is recommended, and so we will find out exactly what the damage is and hopefully where the leak is. If it's all not to bad I think we will insist it gets repaired properly, as to be honest we did really want it for this summer's holidays, and family are also borrowing it to take away. But if the report looks bad then we will have to insist on a refund and if not then start with the small claims proceedings. Thanks for all the info on this by the way and how to handle things with the seller. I will keep you updated with any future developments. The seller also sells caravans on e bay and has for a number of years so I have done a bit of research and he appears genuine and has 100% positive feedback with no complaints so I am hoping he didn't know and that it has just not been picked up by the company that did the survey and that they are responsible.
