Typically, the front section of a cargo bed enclosure is permanently mounted to the truck and does not open, so if it is a 2-piece setup, it usually opens about 1/2 of the bed area, and a 3-pieces opens about two thirds of the bed area and the last section is holding the other two. In this case, the front section is mounted with hinges and gas shocks so that it can raise up to completely expose the entire bed area. This can make the security of having a cargo bed enclosure also very flexible for cargo.
