My 2 cents on covers. Lived in central New Hampshire during the eighties and had at that time a '37 Coachmen Class A. Parked on cement with 2x6 pressure treated wood under each wheel including the tag. Tried a full cover the first year and what a mess in the Spring all kinds of black streaks etc. Cleaning took days and was labor intensive...after that no more cover! Used to go up on the roof after a snowstorm and take the snow off with a push broom. No more problems with the finish. In Florida I bought a rain cover for the harley 'cause it was outside under the porch one block from the ocean. Had all kinds of moisture retention problems with the cover on. Finally ditched the cover and rinsed as needed with a hose. Believe it or not salt will get under a cover. I say try a winter without one before you make up your mind.
