 First - a disclaimer; this is my first new vehicle in 11 years.  The technological leap was huge, so by comparison to my Honda Element, the 4Runner is amazing.  I use this for hauling, off-road, camping and outdoors activities.  I'm just starting out with it, but the fuel economy has been great - much more than I expected.  Highway travel has been more than 24mpg!  Bopping around town takes me down to 21.5.  I've been carefully recording my fuel use because frankly this far exceeds the window sticker fuel economy of 17/21 with 18mpg average.   Cargo space is great... very comfortable... plenty of power and looks great.  So far, so good!
