Time to take the top off, and I am considering getting a portable carport. I keep my daily drivers in a garage, so the jeep is relegated to outside. I am looking at the carports that are made out of metal. Size: 12 x 21 6 feet tall. Cost is $700. Tired of trying to cover it up to keep rain and dew out. Anybody have one of these. Pros? Cons? Probably won’t keep pollen and dust down, but maybe it will help on that as well. Thanks!
