My joinery is not as craftsmanlike as Simon's but its cheap, effective and thin ply makes for a lightweight carcass. I use this two section unit in the boot section. The top half comes out when seats need to go flat for the bed, otherwise it includes a pull-out shelf on which I can place the single burner portable cooker etc for picnic outings under the shelter of the tailgate. The unit is held in place by the DIY back seat hook-over headrests. The design works really well (click images to enlarge)
Under the bench seat I made slide in brackets (v quick and easy using aluminium stock stuff from B&Q and mounting using existing threaded screw holes under the bench):
...and then made a
kitchen cupboard unit for all the crockery, cutlery etc that can be stored there and pulled out v quickly for putting in the awning. The whole thing moves with the seat.
When the various bits are removed, they make an instant
kitchen in the awning:
The equipment is not intended to win elegance awards (though its not to tatty). But it is light, cheap to build, gvery effective and useful, and varnished (Sadolin) ply is much lighter and happier dealing with occasional damp and rain than MDF or chipboard (which I have seen used as a cheap option).
And I did indeed think of using that spare roof height above the rear seats but never got a round tuit and now its less important, with kids grown up.
