I do know the initial cost of the cover would have been double that of a standard cover. Bearing that in mind I believe the suggestion Joel had to use velcro and fold the cover up to a standard length during the winter months and re-evaluate when summer/humidity returns and the heat is off. When the humidity builds you may again wish to have the full drop cover depending on the size/type of AC, if any. Another thought would be to check with Dampp-Chaser for a humidistat that has a lower RH setting. I know they make Humidistats with different humidty level settings for differnt parts of the country.
