Fuel Efficiency of Large Trucks
hey, i was wondering.... how many miles do big trucks (i mean 18-wheelers, and road trains, with trailer) get per gallon? is there a record for this type of thing? or do they only calculate fuel efficiency for small to mid-sized cars? i'm guessing a heavy road-train towing a triple trailer would get around... 5mpg highway (since they're only allowed to drive on highway)?
