Don't get too sucked in by the need for a big antenna mounted on the bull bar, a smaller gutter mount will work as good if not better. (unless it is the bling factor you are after they work because the roof acts as a ground plane). Go to a proper radio store and discuss antenna needs with them and you will find that the more reflective surface you have under the base of the antenna the better it will work.
I would not go for a 3 way fridge mounted in the car a quality arb, engal or waeco will last you a lifetime and it is not worth scrimping on a fridge when you consider that you could lose $200+ if the fridge goes at the wrong time.
+1 for the ralley 4000 lights metal case and once again will last longer than the car.
