Since you're so big on what I do for a living - are you an automotive structural engineer? Are you going to continue to fall in a belief that Dana engineers are smarter than Toyota Global engineers? Are they smarter than Ford, Nissan, Dodge, GM engineers, too? If so, why? You keep avoiding that question and comparing to vehicles built for different purposes. Not sure why you can't compare to like-class vehicles.
I've posted pics of dented cabs before, but since I'm such a nice guy, here it is again. And since I know you'll immediately try to blame this on jumping the truck or anything else you can think of, do a quick Bing or Google search on "Tacoma bed denting cab." It's a very common problem when people carry load... that's what happens when you have a flexy frame.

If ford engineers are so smart, why do the only use it on one truck? If it's so amazing, why don't they use is on everything. You're obviously so arrogant you're not getting the point of why I compare it to heavy duty trucks.
Here it is Barney style
Tacomas and the like are light duty. Do you know that that means? They do not carry a lot of weight.
Ok. Heavy duty trucks are, that's right heavy duty. They carry lots of weight. Are you still with me?
Why is it that a truck (now this is an example) such as a unimog can carry lots and lots of weight off road utilize a super flexy frame? Oh that's right it was designed that way on purpose. Who cares of a frontier uses a boxed frame. Who cares of whatever 1/4 ton truck out there uses a boxed frame. If a mog ( yes it's flexy on purpose. Mercedes has said its part of the suspension) can use it, I have faith that it'll be ok for something as light as a Tacoma. Or even a tundra for that matter. If the guy that made the thing said he did it on purpose, then he has faith that it will be ok. Once again show me where a c channel has ever failed. And no your picture is not it failing.

The second one is Mercedes showing off how much it flexes.
