I'm experimenting with this set up on the weekend thru Big Desert.
Right hand 2/3rd is sealed off with a fixed lid.
Left hand 1/3rd has a pigeon hole with access hatch to spare compartment.
All my rarely needed stuff goes in the spare wheel compartment. Lid closed. It's pretty roomy in there.
Recovery gear, compressor, puncture repair equipment, main tools in pigeon hole.
All the camping gear, clothes, goes next to pigeon hole, above pigeon hole etc.
Can still fold down 2/3rd back seat for long 4x4 Dune Queen bed for transport and other long stuff.
Getting to the spare wheel area is pretty easy. Just have to take stuff from in the pigeon hole.
I'll find out of it's good, or shit, this weekend camping.
