We've recently made up a set of Cargo Rails for the bed and thought I would post them up in case anyone else wants a set.
They mount to the existing tie down tracks on each side but transfer the weight of whatever is mounted to them to the bed sides. This allows you to mount heavier objects to them without worry of tearing up the track system. The possibilities are endless as to what can be mounted, anything from a simple light bar with high lift mount, to spare tire holder, cargo basket, or even a roof top tent for those explorers! Bars are constructed of 1 1/2" square tube.
( bars are not mounted in pictures, just set in place)
We can do these individually or in sets, can be made level with the bed (as pictured), or raised up above bed level. Will come with everything needed to mount but in bare steel thus allowing you to apply the surface coating of your choice.
