Storing car in enclosed trailer

I stored all my stuff from the house when I sold it and didn't have a place for it. I put a fan in it, put a dehumidifier with hose connected to it and drained thru the floor

Have covers over the roof vents so they can stay open and it will not rain in

When I unloaded the trailer I had no signs of moisture damage on anything

When it got real cold I would turn the dehumidifier off, but leave the fan running

One other thing you could do and I'm going to look tonight for myself, get a storeage bag and use decicant in it to absorb moisture. know a lot of people that use them and seem to like the protection.
