The toolbox is a Better Built 77213014 Deep Shotgun Tool Box. It has shotgun latches that don't interfere with the tonneau cover! Unfortunately, the SLE line from Better Built is being discontinued, but we hope they will change their mind. It's the only crossover/saddle style box we've found that plays nice with a tonneau cover! We found ours on eBay here: Item no longer available. If that listing is no longer available, search by part number on google.
This cover pairs great with the shotgun toolbox!
