Mock up time fer the transition lid between the aero cap and the trailer...
Back view...
Corner view...
Side view...
The lid will be attached at the front with a pivot point on the aero cap frame just outside of the aero cap lid. It will be attached with some pins so I can easily remove/attach as needed and so I can raise the aero cap lid separate from the transition lid. The rear will be a sliding mechanism so it will adjust with the rise/fall of the rear of the trailer and the opening of the trailer lid. Rubber tie down cords to keep it taut to the trailer. There will be safety stops as well as safety chains just to make sure the transition lid won't take off back there. We'll have to see how this concept will fair out.
The PVC pipe is just to git an idea of where the sides will extend out and down to. I know I will have to have a 2 piece (rear of truck and front of trailer) of where they will over lap. I'm not sure if I will have to make the sides clear so they can see my truck's rear license plate or not.
