Kristi & Jeff welcome to the forum.  Answering questions is what we do here...............................and sometimes the answers are even right.    

If it were me I would disconnect my batteries, reconnect them, run the genset to charge the batteries and then disconnect them again.  I would try doing this every two weeks, checking my voltage prior to charging.  Then you may be able to lengthen that time, but you would have peace of mind doing so.  Charged batteries won't freeze, but discharged ones will.  Here are Newell's instructions for winterizing.

If covered storage is not indoor storage, then I would do two things.  If the Newell has slides I would blue tape the seams as the bladders will deflate over time.  The second thing I would do is continue searching for indoor storage with at least 30 amp power.  Storage facilities are going up all over and would be worth driving a ways to get your coach indoors.

Good luck in your search.................................

Thank you SO much for the info. I’m getting ready to call a facility. I’ll review the Newell info. 
I was very concerned last night but after some research I’m feeling bettter about things.
