SFD, At the bottom, you've got close to 150 inches. As I said the opening is a funny shape, narrowing as you go in height. There is a chart somewhere that shows the width at every 2 inch height increments; it is extremely useful.
Also forgot to mention; if you exceed 96 inches in width you need to lift your cargo by means of shoring by 5.5 inches in order to pass over the side/guide rails.
