Rooftents are a very comfortable way of camping, having your tent set up in 5 minutes, comfortable matrass included without inflating. They are quite rare in south america.
Unfortunately we find ourselves stranded with our car having some engine problems in Temuco. As we are trying to sell that car (see our other advertisement), we are willing to sell the rooftent apart from the car as well. It attaches quite easily on any rigid roofrack/imperial with crossbars.
