No, they do not cover theft from their property. That's up to the owner of the stored material to purchase. Says so right in the contract. The number of cameras and the auto locking gates and 10 foot high wrought iron fence lull you into a sense of security. The fact I had the trailer double locked was not a problem for someone equipped to cut those locks off. I bought a new trailer, it will be locked as well (with the best anti-theft locks money can buy), but also it will be equipped with a GPS locator in case thieves want to help themselves again, and it's insured against theft and damage this time round.
