Well, I have some anecdotal evidence at best that weight isn't a huge factor in mileage.
I borrowed my Dad's 03 F150 4x4 5.4L auto, to haul fence posts and rails weighing about 1500-2000lbs. I drove 30km to pick up the posts and 70km with them and for both trips averaged about 14.2L/100km using my uncalibrated scangauge. The truck weighs around 6000lbs so I increased this by 25% to 33%. I did notice that it glided better in neutral when loaded up. I did do more gliding though when I had the load on as the roads were better for it and it seemed more worthwhile.

I guess this doesn't prove anything but it's somehting to think about.
