Query: How long is it, really?

Sorry, haven't bought this (yet). But I wanted to point out that the product details list the length of this item as 81 inches. Although this is the part number recommended for my 2000 Ford Ranger short bed truck, my truck bed is only 72" long. It's not clear if this will really fit, although it's what is recommended. Is the 81" length the length of the shipping box? Based on the product details, I would not buy this for my truck.
