Hi Luke,
Very nice set-up you have there, but I'll get in trouble if I travel without my spare tyre during my off-road adventures LOL
It's like Murphy's Law, when I have the spare, I never get a flat, but I bet as soon as I take it out, all 4 tyres will probably go flat. hehehe
I still like the way you moulded the speakers into the floor and kept enough luggage room space there.
