I struggled one what to do as I like to bring different thing depending on what type of riding I'm doing, I picked up these E-Track Rails, Cut them to fit and was able to position them that I could drill threw the bed liner on the High ribs and use 1 inch length 1/4" bolts with fender washers and nylon lock nuts underneath. now I can pretty well snap in a snap lock easily to tie down any thing, tool boxes, coolers, chain saws, spare tire, jacks etc. Total project cost less than $300 cdn
