Does anyone know if there is a tent that fits the back of the Roomster?

Having seen this idea in America i wondered if a tent fitted the back door of the car. This lifestyle car was made for this!

The tents i have seen have an elasticated hem that fits all around the back of the car sealing it, and also leaves a 8 berth tent

thanks Alan:)

Sure you could get one made. I mean after all a tent is essential;ly only some canvas or ripstop nylon and a couple of pieces of aluminium tube.
