Price here in STL for inside storage varies on the location in the metro area. It goes for about $95 downwards. Downwards prices are for those locations further out in the rural areas. There also might be a factor in the price for the length of the trailer. The quote I received a couple of years ago was $50 a month for a 27' Safari, 50 miles from downtown STL, to $95 for the same trailer only 26 miles from downtown.
Currently I'm paying $40 for an outside site about 4 miles from my home.
