Most prominant probably being that weight has a much smaller affect on FE than you'd think.

i could see this being true to the fact that once you have the truck moving it wouldn't take as much to keep it moving, just like any vehicle. my mileage shows really low accelerating but then levels once im maintaining speed. maybe the same applies to trucks?
