You and Chuck are right, Rocketman. The reason I mentioned my statement was because back in my horse/camping/trailer pulling days, my 350 Chevy truck would get better gas mileage than the people I was camping with who drove 6 cylinder trucks. One guy I traveled with had a 6 cylinder T-Bird pulling a horse trailer and got about the worst mileage of the whole bunch. But a lot of things do go into mileage but normally Greg would be right. But just having a smaller engine doesn't always mean better gas mileage.
