Here's some of the things that I've tried for secureing & fastening things to the T's bed:
Big carriage bolts, washers & wingnuts seem to work well to secure things to the bed rails.
Here's another idea - on the Moab trip, in April my bed was loaded with gear, tools and parts, including a steering rack, halfshaft & a second spare. I traded Alrock for this cool cargo net made by Safari Strap with tie down straps (almost seems like the net was made just for the T as it fit the T's bed perfectly). The net's tie down straps were easily looped into the bed rail tie downs. That net kept everything in the bed securely in place during all the wheeling. This pic was taken by JR3T (thanks Jeff):
