The Fastback is the basic configuration in this layout. In this configuration the lower side panels will be lowered into the body panels, similar to door windows. The flexible upper triangular panels will rotate to near horizontal position and sit on both sides of the fastback.
In this pickup truck configuration, the fastback is divided into two pieces, which can be stacked up vertically as the partition between the cab and the cargo bed. There are two other small panels required, in order to form a fully enclosed cab space. These can be extended from the inside of the body, or from the fastback.
