Have been discussing the matter of safty on another forum so would just like to add my bit...When abroad 90% of breakins are scum from the eastern block countrys who put sleeping gas into your van...therefore a deterant before they get to the m/h would in my opinion be a better solution...maybe this company has the answer.....Dave.
