Hey, i don't know if you remember, but i'm the one with the truck box that wanted to port it. I just thought of an idea.
Would it be possible to make a port that goes from the top of the box, all the way to the bottom, then turn towards the driver's side, keeping the same dimensions?
EDIT: Remember, the box slopes, so the port wouldn't connect the front and back walls of the box. Kinda looks like it would in the pic.
