The bed racks shouldnt be that expensive. you can probably get the lumber racks that are sold through lowes or the home despot and use those. But I know that I wouldnt want to use two racks that close together on top of a pickup cab. But I am kind of a coward about things falling off/out of my truck ever since my brother had about ten sheets of 3/4 plywood fly out and almost scalp a car behind him.
