Toyota will never be able to build a 3/4 or 1 ton truck and have the same durability and towing torque and when they attempt it, it will have on paper the ability but struggle with the max load.
1) What engine would they use? A Izusu Diesel, oh that is already in a GM
2) The price would be prohibitive as they are already over priced.
3) How about Honda's truck line, or what they claim is a truck.
4) Ford and GM wont go away, just be #2 (Ford) & #3 (GM)
I'm not trashing Toyota alone. In fact I just bought a Toyota Yaris because they build a great small car and I own a Toyota Tacoma because they build a great small truck. The 1/2 ton Tundra 2X2 is not as good as they think and the truck costs more than a 3/4 ton 4X4 Dodge with a Hemi. The point is the japanese build good small vehichle's and is the reason they are doing so well, but it will take more than a decade to pass by our trucks on brute torque and awesome power that our HD trucks can produce and feel confident at the same time.
