Baggy - might help to build lockable storage drawer/s for the rear. I was surprised what you can get on eBay to make your own - runners, locks, handles, tie points, dividers, slides etc - but bought these instead:
DISCOVERY 3 & 4 Drawer System Storage With Fridge Slide 4WD 4X4 – SLX 4x4

... because - no time. They're heavy and expensive compared to make your own with marine ply etc - you can pay more for aluminium (eg the Tanami I had in my 100 were excellent).

I have a few links to bits n bobs I was looking at when considering DIY, if you're interested.

Cheers
