While I'm sure you're right about the quality (rust et al) under the hood, the Tundra, to the best of my knowledge, does not have the pulling power of an F-350. Nor does Toyota produce anything near the F-450, F-550 and so on.

When you're pulling 26K or better, the minimum you need is the F-350.

Toyota doesn't have enough truck to pull what my F250 power stroke does on mountain roads.
I would drive a Toyota car, but my trucks are going to be powerful enough to get up a hill and heavy enough to keep a heavy trailer behind me where it belongs. If you are a flatlander the underpowered light trucks are fine but if you pull heavy trailers in the mountains lots of power, a strong manual transmission for downgrades, and a heavy truck are necessary to keep the dirty side down. It also helps in not running over flatlanders who don't know how to drive on mountain highways.

The Titan 2500 is coming next year. The 3500 will be out a year or so after that.

The Japanese have lots of experience making medium trucks - those UD or Hino Diesel, or similar? Yeah, they're all Japanese.
