Like all seasonal vehicles, an RV needs solid protection for a significant part of the year. Protection for an RV should keep out water and UV rays but be breathable enough so that moisture does not develop under the cover. Two options for protecting an RV include using a portable garage and a large heavy-duty poly tarp. Without any type of protection from the elements, repeated and intense UV exposure will cause the paint to fade and will cause external and internal cracks, including cracks in plastic furniture, shower devices, walls, and ceilings inside the RV. Water, similarly, will allow for rot and mildew to form on the outside of the vehicle.
Protecting an RV with a portable garage is a long term solution. The portable garage itself is a low-maintenance structure and the structure consists of a metal frame supporting a metal or polyethylene canopy. The portable garage needs to partially enclose the vehicle to allow for circulation, and, if a polyethylene canopy is used, the material is breathable and is both UV and anti-fungal treated. Therefore, the structure will keep out the sun, which fades the RV’s paint and created internal and external cracks in plastic, and allows for circulation to prevent dry rot and mildew. The structure itself can stand up to high winds (up to 95 MPH) and snow.
Another short-term solution to protecting your RV is with a tarp, which is usually referred to as an RV cover. Similar to a portable garage, an RV is a heavy-duty tarp made from polyethylene which is UV treated and, because of its breathability, will allow moisture not to be trapped under the cover and cause mildew and dry rot. When choosing an RV cover, try to find one that is custom fit, as opposed to one size fits all. The size of your RV is not only determined the vehicle’s dimensions but also by any appendages, such as an air conditioner.
