no the Tundra is not and never will be a 2500, wasn't designed to be, but spend some time behind the wheel of one in the real world of work/off road like I have and it will make a believer of you in short order.

I've never been a Toy fan but now that my butt has been behind the wheel for over 100,000 and 8 years I can tell you without hesitation I would buy another. I don't baby my stuff, it has seen it's fair share of WOT and off road, it has never let me down..

They are all building good trucks now, they have to or get put out of business, Toyota could use an engine/trans upgrade to stay competitive and I've heard they are planning an upgrade next year with a redesign engine/8 speed trans?

for what the OP was needing? Tundra all the way.
