the rear seats are sitting on top of the wheel well. They are at a high point of the vehicle.
The cargo space is below the wheel well. And 4 inches shorter.
For the goose gear to work. You remove the seats and raise up the platform 4 inches all around to clear the wheel well
I don't intend to add the sleep platform behind the rear seats. The Goose Gear for my FJ only covered the rear seats and the rear platform was a separate piece. All I'm doing is removing the rear seats and covering them with a flat platform.
