 Before your purchase please check out the owner forums and reviews - specifically regarding the engine and transmission.  After owning many long lasting and fantastic vehicles from Toyota,  I never thought to do much research given my ownership history - my bad and lesson learned.  My truck's issues included a transmission which continued to hunt for the proper gear regardless of grade or terrain, a hood which vibrated constantly at highway speeds due to multiple broken welds which could easily be seen from underneath, and unexplained engine power loss at high speeds.  Dealership was never able to help with the transmission or engine glitches.  After four weeks of driving in frustration I had enough.  I know I am not alone, just read the forums and reviews from others.
