Needed some tie-down points in my recently acquired truck, so I went down to the steel yard and bought a stick of 2" angle, 1/8" thick. Also welded up a spare tire mount. Total cost, about $24.

Spare mount

One of the (4) floor mounted tie downs

Under each top rail and a small one up front on the floor.

Added some squares of 1/8" steel underneath bed for added strength

Spare tire mount - still have to get a big bolt and drill the hole for it.
