They still have a little ways to go. I saw a frame strength test, and a handling test and it was a ways behind the american trucks. But if they beef up the frame it would solve most of these problems..
I also say that video on you tube and from what the guys at our local dealer ship said is that they took the tow package off of the tundra frame used in that demonstration which took out the rears main support. Also they said that there is very few tundras that dont come with the tow receiver factory.
