I don't have my TM up, but I would think its much more than 60" wide. The 60" would not allow a full size person to sleep on the front bed. The TM is 7'7" wide outside wall to outside wall, so the bed is only a foot or so less than the TM. It's the same as the rear bed, so it's at least 72 to 78 inches. Remember width is the question, not length.
Here is the floorplan link.
