We have always had our MH covered. I know they are made for outside but the weather can damage any finish. I like to keep covered for the roof more then any other part of the finish. We don't have power to the coach but don't find that a problem. We run our MH every 2 weeks along with the generator for 1/2 hr. or about 30 miles. we run the MH for the tires more then anything else. In Florida you get to use your MH more with the good weather, so no power again I think is no big deal.
