Some people will do anything to steal your van.
Last November we were living in a caravan on our front drive, whilst our house is undergoing flood repairs and it was stolen, lock, stock and barrel, including all our possessions, clothing and the family pet. It was a traumatic experience for all our family, hopefully never to be repeated. The insurance company had not put any security devices on it at all, it was nose down the drive, with an steep incline out of the drive. It was also a very heavy twin axle Besscarr Cameo 635, which needed 6 men to steal - seen by my neighbour, who rang 999, yet the police took 20 minutes to come out and didn't raise the local helicopter. Everything gone, in a couple of minutes. If it hadn't happened to us - I wouldn't have believed anyone could stoop so low. What would have happened if my kids had been inside it? I had only been out of the van about 20 minutes.
Scumbags - the lot of them.
