Sounds like amateurs the only thing of any worth was the money, it sounds a bit like a youngster probably feeding a habit.
You are right in not contacting the police, they wouldn't be able to do anything and all it would do is increase your home and probably motor insurance.
At least you've had an early spring clean.
I have looked at the options as Rae has offered to fit one for me but looking at all the measurements I don’t have enough clearance between the doorframe and the kitchen cabinets to fit one so will get lots of help and advice at the frog for now I have a leather strap on the inside of the door fastened to a rear seat belt so the Hab door cannot be opened from the outside for now and I have put 2 alarm censors in the van for now.Sorry to hear your bad news Annie
Perhaps you should consider fitting one of these ( see photo) or both !!
I would be more than happy to help our top engineer Rae fit it at one of the meets,
Anyway good positive attitude. Take care Alan
