RJVivaroL2H12018

Hi. I am trying to get hold of a technical drawing that shows the interior layout and dimensions of the 2018 Vivaro L2H1, but am finding it impossible. I can find data tables with some dimensions on, but this does not give what I need. Do any of you good people have access to these, or indeed be able to advise where I will find them, please? Thank you in advance.
