Storing car in enclosed trailer

I have been thinking about getting an enclosed trailer to store my Dart in. I currently rent a storae unit about 15 miles away, and at almost $80 a month a could pay for itself in a couple years, plus my Dart would be at home and easier to get out and enjoy.

I'm in the same situation. I thought about trading or selling my open car trailer for an enclosed one so I can keep another car at home and bring my storage fee down some.
