Hi Guys, many thanks for the welcome to the forum and the advice, seems tragic there is so little we can do to stop these people, anyway will persevere. I am planning to look at several measures to fit, e.g. Mech Lock, Disklock etc as well. I reckon if I fitted deadlocks I think they would be obvious they were fitted as there would be an additional key hole on the doors which hopefully would be some kind of visual put off. Anyway will let everyone know if I get a reply from the Lock4Vans people.
