 Bought this truck brand new.  Not the fastest truck but 20 MPG hwy & 15 MPG city is very good for a full size V8 truck.  This is mostly thanks to my truck having the updated 4.6L 16V with the 6 speed transmission.  This truck is Lexus quite too.  Only sound is the exhaust which sounds like a quite version of the old glass packs (very sweet).  Only problem I've had with this truck is any time I have an electronic device in the truck (cell phone, GPS, MP3 player etc) the tire pressure monitor goes off.  Dealership recommends I not us electronic devices?  Other than that truck seem very tough and reliable.  Easy to park due to turning circle.  Highly recommended if your looking for a truck.
