If you saw them taking your caravan, would you really want to stop them as they simply do not care. Whether you are 6'6" tall and built like a rugby forward, your body would be no match to a knife.Hi Sam & Woodentop . If it had just been stolen I would love to catch them in the act of moving it out on the road. I have plenty of security measures at home where it is kept. It is more for Insurance purposes I suppose and retrieval in the short term rather than later down the line as insurers always deduct a hefty amount from the value. Cheers Nick
