I have a Calmark Cover for our 33' Cedar Creek. I only use it over the winter and it has a zipper for the door to access. I tie it down with ropes and it works well. I store it in a wheeled garbage can with a lid. I have the front of the cover at the top of the pail. I tie a rope around the front of the cover and climb up the ladder then pull the cover up and over the trailer and drop it over the sides. In the spring, I pull the cover up on top of the trailer and have my wife guide it into the pail as I slide it off the trailer. Roll it into the shed and close the lid.
