Great Truck
 This is my first toyota and I will most deffenently buy another one.  Like all companies including the big 3 there are some issues with some of the trucks not all of them are perfect.  Just wanted to mention that after reading some of the other reviews.  My truck has not had a single issue.  Drives great rides great performs great. The gas mileage kinda stinks on E85 but the cost of it makes up the difference and you get more power running it.  Only thing i noticed was a bouncy ride on highways that have the groves to prevent water build up.  After the first tire rotation that went away.  If your thinking about buying a truck buy this one.  You will love it.
