Yet another divider DIY question

Like others I want a bed divider that doesn't cost $300 but lets me put stuff in the rear of the bed and keeps it there. Those depressions in the composite bed near the wheelwells look like they're sized for a 2x6 although I haven't actually checked. Has anyone tried working from that as a starting point?

 

A 1x6 will lay flat in the slot. A 2x6 will stick up a bit.

 

Spring loaded adjustable shower curtain rod will work to retain light loads.

 

That's a good tip.

 

2x6 works real good.....!!

 

Or you can do what I did and take a big rig load lock and cut it to fit so now I can adjust the bar for all lengths in the bed
