I think you will fit in here quite well Geoff!
I have to admit I didn't look under the 'Shopping Carrier', but as they have done away with the 'Tool Tray' on the Bulk Head, I suppose a suitable 'Toolbox' will be required under there.
As I'm too tight to buy any 'Tupperware' boxes. I'm considering using a wooden 'Mirassou Vineyard' box with sliding top - 37 x 26 x 20cm. Do you think that would fit in the available space on a current 4/4?
