Outside Storage Ideas

I have a 68 Dart that has been stored indoors for 20 years or so, I have lost storage and dont want to keep it in my work space. So I was thinking about storing outside on a gravel parking area, with heavy mill plastic over the gravel and a water proof breathable cover. I dont want a hoop house. Anybody see a problem with the way I want to do it? Hopefully it will only be for a year or so.:dontknow:
