Yes, and their rear axle looks like a toothpick.
That is a statement made by someone who is obviously prejudiced to the big three and ignorant of comparable half ton rear end specs. What would you say the big three rear ends compare to? A strand of silk thread? Tundras may have a lower payload, but no part of their rear end is the weak point. I suggest you do a bit of research on Tundra rear ends. It is generally accepted fact their rear ends are more comparable to a three quarter or full ton truck. Not saying the Tundra is a great truck for a TC, but giving credit where credit is due.
