That was one of the ideas I'd seen at YT. It was great because I realized a handmade job could be done, atleast. I only wish he had more pics closer up to the details and more his process.

When I do something it will be basically like this. Only, I want to be able to put a seal between the framing and the body of the truck. I want NO leaks during hard rains. I also want to be able to put my Thule roof rack up top as opposed to something welded up to the cage frame. This way I maintain adjustability for different sized loads.

Thanks for posting. Anyone else with any other knowledge please feel free to share. I'm open.
