There is a similar discussion on tractorbynet.

They also mention airbags as a potential cause.

The going theory is, if they are over inflated it can take a significant load off the front and rear attachment points of the leaf springs and concentrate load where the airbag meets the frame, putting high stress on a single point of the frame.

I have no idea if there is merit to this but it was interesting discussion.

Having done the 1 ton 4x,  4 door with big camper and boat and always having wondered about the bouncing and porpoising, and looking at this makes me wonder if truck frames only get static tests for their ratings or if any mfgs actually do any dynamic testing to address the issue of increasing dynamic loads while rolling.   

It also makes me wonder how much the giant camper in the bed and the trailer on the hitch weighs and how much over the payload capacity of the truck it all adds up to. At least some of these pics make me wonder if it’s a “play stupid games and win stupid prizes” situation.
Oddly enough none of them are first Gen Tundras where the frames just rotted and broke in half.

OOOHHHHHH!!!!
YOU DONE IT NOW!!!!
The Toyota Fanboi mafia is getting the pitchforks and torches ready for a full-on assault.

This plus porpoising makes a lot of sense with regard to frame failures.
At least the photos are not from rust...

[Rob]

could it actually exaggerate porpoising?

I literally was laughing out loud when I read this.

Wonder what the bare frame weight differences are over the years??  They've most likely have made them to lite!!

There comes a point when drilling to many holes and putting to many bends in the wrong place, things WILL snap!!

There is something to be said about having a "solid" frame verses a weight saving frame!  But that goes for everything else too,  just imagine what today's pickups would weigh if they were built like they used to be!!??  Less plastic's and stronger frames!!

Not sure if it will bring out the fanboi’s, but it for sure riles up the hater’s…

I like Toyota,got one sitting in the driveway.
With that said there all junk these days.
Chevy,Ford,Nissan,dodge,doesn't matter.
Anyway to save a buck in the manufacturing process.
Anybody that works in manufacturing of anything will tell ya it's true.

Quality control is in the toilet ,is why these frames are junk.

There has not been a good truck made since International and Studebaker quit making them.

Pretty sure the white Ram / camper combo is a modified frame - has nothing to do with the manufacture

I thought it was just a modified/cutaway bed. Looks like a regular crew cab long bed. 
Also I searched that guy on the gram and he’s got a new one now. Same brand make model etc so he must not have been too upset about his truck breaking in half.

I would bet my next check the bed isn't the only non-factory feature on that truck.
