A couple of questions for Lang 48" Patio owners: I have read that a sliding upper rack is now standard. Can anyone confirm this? Anyone have a picture handy? What is the exact width including the table/shelf? I found 1 post saying 42" but I need to verify. I am trying to figure out how I will get it into my backyard. I also read that there is an option to have a shelf that folds down. Anyone have this option? What is the width when the shelf if folded down? Does this option reduce the amount of space/surface area of the shelf? Any pictures of this? Thanks...ordering a 48" Patio today!
