Having now got my twin camera system I now have to figure out ow to put it on/in the MH. How have others fixed the camers to the rear of the van? Twin camera fixed to the top . It looks like my Autocruise Starfire has a shaped moulded section up there. It may look pretty (perhaps) but I don't think there's a flat bit where I need it. Camera system supplier suggested Sikaflex. Any pictures appreciated.
