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.
