@Strigidae nice! I've considered something similar in the back of my truck. I have handles on the side, and I think I could slide some sort of hook into the rear window to anchor it there.
I did have to take off the garment hangers and slide some webbing over a bolt to be able to use them as an anchor point. They use G hooks and i went with adjustable buckles. It is a space that is not used if you dont have passengers. I absolutely hate packing straight up to where i cant see out the back windows.
Nice idea !! Some of the fit outs here (using steel mesh) build a top shelf into the cargo bay like this !!
Anyone make their own chuck box yet? Pretty tired of the plastic bin ive been using. It works well but im ready to make something fancier.
