If my recollection is correct, the pathfinder and 4runner has the same size engines which are 4 litre V6. The FJ has the same engine size like the 4runner but is capable of towing something like 5000 lbs alot more than the 4runner. What makes the FJ able to tow more? Is it because of the heavier weight on the driving wheels so that the tires have better traction. My next door neighour is not too impressed with the Pathfinder gas milege and if the FJ could pull more because of the heavier weight, this will really make people want to buy one with a diesel. Any info is appreciated.
