摘要： Air ducts mounted to pass through the bodies of campers or trailers and provide flow paths for air from relatively high pressure to relatively low pressure areas adjacent the outer surfaces of the vehicle bodies. In their most useful forms, the air ducts run from side to side through the vehicle bodies, and serve to reduce air pressure differences between the sides of moving vehicles caught in strong crosswinds, and thus protect the vehicles against the danger of turnover in such winds.
