This shelter features a reinforced bottom frame with an extra row of horizontal support bars for superior stability and wind resistance. The heavy duty one piece seamless cover resists tearing, fading, Uv, water, wind, and snow. Removable double zipper doors on front and back allow drive through access or rolled up for airflow. Four roof vents promote air circulation, reducing heat and moisture. The dome roof design provides more headroom than traditional peaks. This 12x20 ft shelter works as a garage for cars, SUVs, or small RVs, plus storage for garden tools, lawn equipment, and patio furniture. Tool free assembly with easy connect steel pipes, one piece cover, hardware, and clear instructions.
