The carport provides stability and strength to the unit, increasing its wind and snow load capability. It is a multi-use shelter that protects RVs and campers. The gray roof and steel frame will protect your cars from rough weather or other debris, and provide a sheltered area for vehicles, protecting them from rain, snow, hail, and sun damage. Important Note: Please keep the roof clear of snow. Excessive snow can damage the carport and create unsafe conditions. The manufacturer is not responsible for damages resulting from improper installation or severe weather conditions.
