The first and second deck sides extend in parallel with each other to define a deck plane. A first extension structure is connected to the first deck side and extends inwardly from the first deck side. The first extension structure includes a first connection structure and a second extension structure connected to the second deck side and extending inwardly from the second deck side. The second extension structure includes a second connection structure arranged a distance from the second deck side. The support deck includes a first cross-member with a first and second ends, the first end being connected to the first connection structure and the second end being connected to the second connection structure. ## Claims ### Claim at position 1 -13.
