Thats what i thought but I do. Well as the camper bedroom pods are stretched tight i wondered if this was causing the problem. I suspect though that the draught is actually coming through the material to which the zip mechanism is attached, which is in turn stitched to the tent canvas.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
