I have owned 3 Tundras since 2000 and none of them were stellar fuel economy performers, but that was not the reason I bought them. I knew they were a little thirsty. Of the 3 I have owned, not one of them has ever been back to the dealer except to be traded in. Reliability is more important to me than a few mpg. Everyone has to decide what is right for them.
