Thanks for the compliments!
I made the tailgate bars from 1" aluminum bar stock and yes they fit in the action packer.
The quick fists on upper horizontal sides are for surf fishing rods, ones on rear vertical sides are for beach umbrella or canopy poles (trip to beach at Cape Hatteras every summer).
Last pic shows addition of Swag offroad action packer holder and 5 gal fuel can holders. With two bikes in the trailer I was having issues with slight wag at about 50 mph. Once I moved the weight of the gas cans and box forward that solved the wag.
