How much of your driving is on the highway, rather than deliveries around town ?
Around town, the benefits of aeromodding won't be huge.
The effect of using AC full tilt in city driving can be massive.
I've seen it as bad as 50% extra fuel consumption - and we get nowhere near Ozzie temps in summer.
When you're doing 100kph, the effect of AC on fuel consumption is quite limited.
