when you see damage like that it makes me wonder if they are better left open,Advanced locking system kept them out but they had a good go on this Dutch couples Hymer in Portugal. Met him in Spain last night as he was getting out of Portugal. See the photo

totally agree makes ,no sense at all ,I can never see the logic of thieves (praps there is none) who would try to prise open a steel door, when there is a plastic window a metre away that can be opened in seconds with a wood chisel.
Not sure what locks he had on his door but I really don't like those locks that fold over the door,they just scream no one home to me,I'd certainly never fit one. My preference is the cheapo standard locks fitted to the mh,easy to get thru without causing major damage. If they want in,no lock will stop them,but if there's some doubt as to whether or not it's occupied then I think they'll go for the ones that it's obvious are unoccupied.
