As far as grades are concerned, you get an advantage with more weight going down hill to counter the disadvantage going up hill.
Also, if gearing had anything to do with the reason that cars get proportionately poor mileage compared to large trucks then it would simply be a matter of changing the gearing of the cars to increase their mileage. The fact is, cars are already geared as they need to be to most efficiently do their job, as are trucks.
