There's a lot of [rusty] steel, but it is untriangulated. You could put an intermediate layer of steel birdcage under the aluminum and over this:

...and have something that is ready to roll end-over-end.
In miniature, I expect that's what aerohead is doing.
Don't you agree that the redwood strips over the windshield, with the front lip, on my Baja resembles the aerocap on your truck? Hand-selected redwood or spruce with properly lapped joins and epoxied hemp or basalt tape wrapped joints and it would be ready for boat [tail] wrap.
Better the windshield is a hexagon of glass with a triangle on each side.
