Toyota getting educated, changing Tundra's model mix

[Baba Booey]

Here is a description of the newly designed F-450, which has a payload rating of 6,000 lbs. and a tow rating of 24,000 lbs. Note that it has a boxed frame only in the front:

"The frame is a modified and stiffened version of the one-ton frame, with a completely new fully boxed front section that uses longer, wider sloping frame rails to accommodate the bigger 6.4-liter twin-turbo Power Stroke and massive intercooler."

Tundra ain't no Peterbuilt!

As for 1/2-1 ton trucks, it's all about cost of manufacturing a huge boxed frame. It's very interesting that ALL of Tundra main competition have fully-boxed frame...and all their competitors have been making reliable & durable trucks for a very long time for the true hard workers of America. They know a few things or two about heavy duty trucks.

As you can see, Toyota Tacoma's frame (partially boxed, like Tundra) isn't all that strong compared to it's competitors...i don't think that you can use the Peterbuilt argument there. Therefore, i need more convincing to believe in this "Tripletech" frame design....

Here is what i wrote before:

"Did some more reading. The C-section (if it's tall) is good enough to withstand vertical loads...thus, you can get away with it in the rear bed. The problem with C-section frame is that it is bad with twisting forces (e.g. off-roading) and side load (e.g. accident). This is why the big HD trucks can get away with using tall C-section frame in the rear 1/2 of the vehicle...easy and cheaper to produce and does the job good enough for the average truck owner...BUT it is NOT necessarily the best solution in terms of frame strength and durability.

This is why the front of the Tundra (and all trucks on the market today) are boxed for crash testing strength and cabin stability while the rear bed is C-section because the bed mainly deals with vertical load.

Therefore, having C-section frame in the rear has NOTHING to do with ride comfort or handling. It is meeting with the needs of most truck owners."
