Just curious. I have an '06 Classic. Owner's manual says it hold 4.8 gallons of gasoline. My wife has an '09 LT and it holds 5.3 gallons. I've looked at both, tried to at least visually compare both tanks and they both appear to be the same size, at least on the outside. So where is the difference in fuel capacity that the .09 holds half a gallon more gas? Anyone know the answer to that question?
