Installing and removing a breathable cover is a bit of a process so I don't do it during the camping season but would if it were just a 5 minute job. However, for winter storage I've always used a breathable ADCO cover on any trailer we've owned that I've had to store outdoors over the winter. JMO, but if you can't store under a carport or inside some sort of building covering the trailer with a breathable cover is the next best thing and far better than just leaving the trailer fully exposed to the elements. Others of course will disagree but that wouldn't ever change my view after having used covers for the last ten years. This year an opportunity arose for me to store our trailer inside over the winter so I took it. :B
