 I have owned my 2001 Tundra for almost 4 years now, and I have put 50K miles on it so far.  I have loved everything about this truck so far.  Reliability has been excellent.  I have taken the truck to the dealership once when an O2 sensor went out  (fairly common problem among Tundras).  The warranty fixed it for free.  The gas mileage is as advertised (about 18 mpg on the highway), and the 26 gallon fuel tank gives me plenty of range.  I can fit a baby seat in the back seat, but the front seat will be a tad tight.  I am 6'4", and I have plenty of room in the front seats.  The back seats are OK for short trips, but I would not want to be back there for more than an hour or so on trips.
