My Du-Ha underseat storage showed up and I installed yesterday. This unit has more overall storage, it's deeper, than the one I had in my 2015 Denali. Easy to remove OEM storage tray and install the DuHa. When you try and put the handle for the jack back in place on the drivers side it is hard to get the nut started, just take a deep socket and bend the threaded stud up about a 1/4" and it will start much easier. Very pleased with this product and they way it fits in place. Link to DuHa https://www.du-ha.com/gmc-silverado...ilverado-sierra-heavy-duty-crew-cab-2016.html
