Covering the bed for storage

[Montana_329]

I have a question I hope someone can answer today. We have lived in our 3575RL for the past 4 months. Tomorrow morning we leave for home in Las Vegas. We are storing the trailer here in Michigan. It will be stored til next May in a heated (45 -50 degree) storge warehouse. Do we leave the bed completely uncovered or can we keep the sheets, comforter and bed spread on? I was wondering about humiidy causing mildew. What do the rest of you do in a case like this. Need to know before tomorrow morning. Thanks in advance.
