got a letter from caravan guard , this morning about caravan Insurance , so i called for a quote , and when it it came to caravan security , i said i have 2 hublocks and 1 hitchlock and its alarmed , also has a recording security camera trained on it , he said have you got a wheel clamp , i said no , he said very sorry we cant insure you unless you have a wheel clamp , not that i am bothered as i am happy with the caravan club , but i always like to phone around to make sure i am getting a resonable quote , so is a Wheel clamp classified as better than a Hub lock
