Oops!Jump the gun on the official side,sorry about that I will fall into line and follow official protocol!You are spot on Cuppa,the thought has crossed my mind about sleeping in there but yes that does have inherent problems,we do own a tent and I am inclined to still use that for longer than the weekend trip but I suppose for now weekend escapes are what we are gearing for and as we live on the doorstep of Fraser Island that is our usual escape weekend.The tent thou is such a pain to setup and a rooftop setup is looking more appealing but I have to entice Mrs Briss into climbing a ladder and I don't know how long she will put up with that,we are looking at finding a fishing spot that day camp that night and then move on again say in a couple of days.If I was to go rooftop I suppose that would change the roof rack design and perhaps I would go with what you have suggested Cuppa!
