With the onset of the storage season coming on in a few months I am looking for cover suggestions for my Pup. The manufacturer says it is 17' long but that must include the tongue since my box size is only 10 ft. I have an AC unit on the top too. I understand I need a breathable cover to reduce dampness inside. Any recommendations will be appreciated. I will be storing it in my backyard on the lawn, any precautions concerning the tires, should I block the trailer up off the ground? TN has a winter rainy season so I want to be sure to protect it from the effects of the rain and some snow from time to time.
