The Quattro DD is the only twin-lounge, twin-axle, six-berth on the British market for 2017. The reason why twin-lounge caravans are so popular is that they provided two very separate areas for two generations. The idea of two long lounges remains a brilliantly simple design concept, with immense versatility. The layout gives you four single beds (two at each end). Or two double beds, each more than 2m long. Plus two bunk beds to lift into position over the rear single beds. It works for four, making one bunk bed and leaving the settee on the opposite side as somewhere to eat breakfast. It works for four when the kids emerge into the teen era; they can have the singles at the front and mum and dad can make a double at the rear; their separate area. And it works for two couples, each making double beds.
