Deposit down- Now I'm no sure I can tow it. manual not clear

I had a tundra before I bought my diesel and it was a strong puller. I had the tow package with 4.30 gears and trans cooler though. I think you would be fine if you put a before hitch and trans cooler on your truck. I think the tundra comes with a 4.10 rear end even without the tow package. The factory hitch that came on mine said maximum rating was 11000 pounds on the ball mount. I think for a few hundred bucks you can be good to go.
