Love the Tundra and my company has purchased 10 and put 1.5-1.75 million or so miles on them but they have their issues:
If you are tall, you will hit your head on the side curtain getting in the cab (6'3").
Change the transmission fluid. It is a sealed tranny and will cost close to $300 for a shop to do it but will not downshift correctly if not done every 75-80k. The fluid change remedies the issue.
The accelerator is so touchy, not a good vehicle to teach a kid to drive on if you don't like whiplash.
Interior door hinges break.
Finally, they don't pull for squat. Even a 20' boat will collapse the rear suspension or a Ranger on a double axle trailer. Also, fuel economy goes to like 9 mpg. They do drive like a car and will fly, they are fast and loose.
