Do not, under any circumstances, consider a Toyota Tundra. They are a giant heap of flaming crap. Do NOT buy one.
I'll be up front. I work at Ford. However, I'm not biased and regularly recommend vehicles from other manufacturers when Ford falls short. For instance - while the ridgeline is ugly (to me), it's functionality simply cannot be denied. As someone else said, you can appreciate some of the tradeoffs they made.
However, the Tundra is another bad truck job by Toyota. The issues are too numerous to go through - extremely weak and flexible frame, bed that bends when loads are put in it (to the point of the tailgate jamming shut).... Do. Not. Buy. Someone else mentioned rust - they're still having a major rust problem because of one of thier suppliers. That one isn't exactly their fault, but it doesn't really matter whose fault it is if your frame rusts out.
Their Tacoma on the other hand is a good vehicle. I think that currently it's better than Ford's Ranger offering.
