True, true. HINO has many an option in the heavy D, especially with low sulfur coming on line. Played with a few of the products of the HINO variety in my current job; surprised that anyone knew that they screwed the FJ together. Respect for my new FJ friend! 3000cc was plenty good for 20+ years, a few more wouldn't hurt.I don't need or want a fast truck either, so like carrotzilla said a smaller diesel is the answer (just not too much smaller). The 3.0L TD will do just fine for me, get better MPG's, have buttloads more torque and crawl like a unimog.
But really I don't care. Find some HINO motor and slide her in there. Come on Toyota! Take more of my $$$ and make me an even more hardcore Toyota lover.
