Sold my Tacoma but kept the tonneau. This is a matching 1/8 inch thick tonneau and Kobalt tool box (both aluminum treadplate), that was custom made for a 2008 Tacoma but should fit all similar models with a tapered composite bed.
Have keys for the Tonneau T-Handles, Toolbox and it also comes with a PopNLock gate lock (also with keys).
This is too big to ship but if you are willing to come by Huntsville Alabama you can pick up the tonneau, box and gate lock for $350. This price is for a tonneau, toolbox and gate lock.
This is built to last and protect your stuff. (note this top is not water proof and I can provide a plastic bin that sits inside and underneath the cover).
