I need to drill a 22mm (7/8") hole in the rear of my 2002 Bailey Senator Oklahoma to fit a small CCTV Camera (see "CCTV Camera at rear of Van" under "Towing, driving and safety" discussion).
The outer 'plastic skin' cleary has an air gap betwene that and the inside 'wall' of the rear of the caravan. But what is this made of. I have purchased a Mandrel (for wood, masonry and metal) and a 22mm Holesaw which cuts a cicular hole of the correct diameter.
However, could this rip / tear the outer skin of the caravan? And what's te material immediately on the other side of the skin i.e the 'wall' of the caravan?
John Glassey's been incredibly tolerant of my multiple questions; but I cannot afford to get this one wrong !!
Thanks for any responses. John
