well it sounds like you have more than condensation. The head isn't all that heavy, you can just pick it up. I mean it weighs more than a birthday cake, but isn't unmanageable. I was saying it takes a good hour of driving at highway speeds to get all the moisture cooked off, but I only really noticed this on my trip from san diego to montana during the winter. I've noticed it occasionally over the last 25 years, but only during the really cold times.
