It's a Toyota, what do ya expect?
 I'm approaching 190k miles on my '06 Tundra.  I drove it off of the lot with 9 miles on the odometer.  The truck is great and have had no major issues with this truck. I have replaced the front brakes twice, the rear once.  I have replaced the serpentine belt and spark plugs only one time.  It seems the older the truck gets, the better the mileage is.  Currently, I'm getting 17 mpg running regular unleaded fuel.  I've had no leaks on any of the seals on the engine, transfer case, or differential.  The truck rides as if it was new, with little road noise, vibration, or any unusual sounds that would raise concerns. If you are in the market and can find this truck with low mileage, I highly recommend this truck.  My only complaint is that it only has the 4.7L 271hp engine, which is weak, but it will pull your trailer if you find the right gear.
