We installed a platform rack onto a 2021 Chevrolet Colorado.  This is a Pioneer Platform made by Rhino Rack and is attached to the vehicle with what is known as a Backbone. To attach the Backbone to the vehicle we secured it to the existing fixed points and weather stripping. The Pioneer Platform has planks with track mount channels accessories pictured such as Maxtrax Recovery Boards, Rhino Racks Spare Tire Holder Straps, and Rhino Racks Stow-it made to hold a shovel or axe.  The load rating capacity is 220 lbs.
