This 18x45x12' metal RV cover with extended panels is a type of structure designed to protect recreational vehicles (RVs) from the elements. It is constructed using metal materials, typically steel, and features a vertical roof design. This means that the roof panels are oriented vertically, allowing for better water drainage and snow shedding compared to horizontal roof designs.

Vertical metal RV covers are known for their durability and strength. They are designed to withstand various weather conditions, including heavy rain, snow, wind, and even hail. The vertical roof design also provides additional structural support, making it a popular choice among buyers.
