Completing the larger Phoenix Black Edition layouts, the 644 pairs a transverse rear bed with a full-width end washroom. It is a four-berth caravan measuring 5.84 metres internally, with an MTPLM of 1,437kg on a single axle. Transverse Rear Bed A bed running across the rear of the caravan is permanently made up and uses the width efficiently, leaving good storage underneath. End Washroom The rear washroom spans the full body width, giving generous space around the shower and basin and keeping the wet area separate from the living space. Parallel Sofa Lounge Twin facing sofas at the front create a sociable seating area that converts for extra sleeping if needed. Well-Equipped Galley Oven, microwave and fridge freezer are all standard, making proper cooking on site straightforward. Single Axle Keeping to one axle makes pitching, manoeuvring and storage easier, while 162kg of payload leaves room for the usual holiday load. Rooflights A Heki rooflight and sun roof bring daylight in from above, which makes a real difference to how open the interior feels. GRP Side Panels Glass-reinforced plastic bodywork resists stone chips and hail better than aluminium, keeping upkeep minimal. The 644 suits couples who want a fixed bed and a large rear washroom in a caravan that remains easy to tow and store.
