Right, here are the pictures as promised.
Sleeping platform
--------------------
The loadbed has a platform made out of ply wood, supported by steel crossmembers bolted to the side of the vehicle. Underneath the platform are 2 large storage boxes that run most of the depth of the load bed. There is a place for the last part of the platform to slot in between the platform and the boxes in order to give more storage room at the back, it can also double as a small table, with one person sitting on each wheel arch ( when doing this the space is rather limited ).

The last part of the platform removed and slotted in underneath to provide a table - 2 of us have sat in the back for a couple of hours, but space is limited
Wingnuts aide quick removal of the platform
Cooker
---------
There is a cooker bolted to the back door. This works well, but with hindsight I would have built a drop down shelf that could have fitted a cooker - this would have given more flexibility and not cut into the storage space in the rear as much ( you need to reckon on the thickness of the cooker when filling up the rear storage area, otherwise you could damage the cooker/you can't close the door )
Lighting
---------
The guy that fitted out Gertrude provided plenty of lighting - 2 halogen downlighters - one by the rear door ( handy for cooking and when sitting in the back ) and one close to where your head is when laid out. In addition to the lighting, there are various clamps/hooks/storage nets for keeping small items neat and tidy/easily to hand
Downlighter just inside the rear door - very useful when cooking at night.
Hooks, clips, bungee cord, storage net and a rechargable Maglite
Reading lights on both sides
Random bag of bits and pieces to hand by the back door
