You're not too late, but I did take delivery on the Tundra today. It is every bit as big as I need. I saw the release for the Titan and also thought about waiting for the Tundra Quad Cab in November. The truck I bought with 4.7 V8, LSD, TRD off-road package with Bilstein shocks, and towing package add up to 1,525 payload and 6,900 towing capacity with a class IV hitch and stock 7-pin plug. It'll handle more than I expect to haul or pull. It fits in the garage and my wife is not terrified of it. And most of all, it looks great and is a BLAST to drive. /forums/images/graemlins/grin.gif If I need more muscle, I'll borrow my down-the-road neighbor's F250.
That Titan will be something, though. I read that Toyota will bide their time for at least two more model years and get a little better at this segment. Nissan gets a free ride (as far as "import" heavy half-tons go) for awhile. I think that Titan may actually help pave the way for general acceptance of imports into the work class truck. Seems like there is quite a cult of loyal Tundra and Tacoma owners who are watching the Titan and curious about what Toyota will do to "draft into the full-size truck market.
Interesting to note that Toyota currently manufactures everything on the Tundra in Indiana with hometown labor. The engine is still imported, but only until next year (I think) when they open a plant in Arkansas.
