The Full Bed Support System is a set of brackets meant to accompany the Ultimate 5th Wheel Connection – Gooseneck version (3220) and the Ultimate 5th Wheel Connection – Toolbox Model (3220-TBX) when installed on 2015 and newer models of GMC and Chevy Trucks. This helps prevent warping that may result from torque forces, and fastens to the frame beneath the rearward bed saver rail.
