Had to pull the EMT off and go back to the wood bottom rails. It was taking ferever to drill the self tapping pan screws into the EMT. Didn't want to spend all day on the bottom rail...
After putting the wood rails back in...it took very little time to build up the sides. Had to put the screws on the outside as I was running low on time to git finished and on the road. This design is a combination of my 2nd and 4th configurations. I pulled the top rails in about 10" in the rear so now it's more tapered from front to back.
I ended up revamping the hatch setup. It's now a single sheet since the 80mph incident damaged the hatch layers.
Time fer piccies!
