Nissan Largo Friends

Hi there,
I have bought my Nissan largo a month ago, I really want to convert it into a campervan but don't know where to start! Any suggestions would be gratefully appreciated!

Thanks guys!

Measure up and draw a couple of different rough plans. I.e cooker location , fridge , seat or bedseat and go from there.
Seen a few done in all kinds of ways.
Search Google for inspiration. Also consider cost.
