I had new screen doors laying around from an unfinished house so mounted 2 at the rear that swung together. Gives me 60" width for putting ATV or Snowmachine inside to work on. Doesn't give more height because of the curvature of the roof and I had to build over the wheelwells so I kept enough room on back for my car or landcruiser. I took roof off to the middle of the wheel wells. Framed in with galvanized channel and Pop rivets, put 2" foam where I could and covered with tin. Not pretty but will do the job. No pictures yet. Have a great day.
