Another option for the deck could be a slide out aluminum deck from under the drop down frame. If it was all aluminum and on rollers or something making it easy to pull out you could make it nearly as long as the drop down portion of the frame and as wide as the unit itself. This way it would be under your awning. As I said a possibility, but believe it would not be cost effective at all. Maybe something other than aluminum could be used but it would have to be light. Light strong materials cost a good chunk of change!!
