Has anyone put this item in the bed of their truck? I have my step-side off right now and am getting it all ready to go back on and am looking at putting these at the top of my bed to allow me to secure items in the truck. At this price with the current discount it even beats my employee discount at Orielly's. Look for the positive or negative feedback either way.
Since I have my rear fenders off it should be pretty easy to mount.

Thanks in advance.
