Since the mileage with the 3.73s will not be hugely better than the 4.30s, and considering you plan to eventually add larger diameter tires, I myself would go with the 4.30s. You'll probably have to order it as most dealers spec the 3.73s on their stock units. As far as stop and go mileage, I would think that the 4.30 ratio would be a wash as the engine would not have to work as hard to get the beast moving.
