3/4ton and 1ton trucks, pivot frame needed/worth it?

Is this what you guys are after ?

I ask this because the frame on my truck is one of the reasons I bought it. I have had 1200 lbs in the bed & flexed it (with swaybar disconnected) till i had 1 wheel off the ground & the space between the bed & cab stayed the same top to bottom & side to side. I have a 2008 Dodge Power Wagon. I am certainly no engineer but it seems to me the suspension should be doing the flexing---not the frame. When any metal bends & twists it get inherantly weaker, right ?

This is not true in many cases. Many truck frames (like my Unimog) is riveted together and designed to flex. Even my now gone 2004 F150 frame flexed enough on bad/rough fire roads to potentially destroy a solidly bolted in box/cabin.

X2 on what 762 said. If the frame is engendered to flex it will not weaken. Skyscrapers are designed to move and flex and they do not fail.

But if the frame flexes enough to destroy a solidly bolted in box/cabin, it seems like it causes an entirely different set of engineering problems that would not be an issue with a more solid frame?

That's just failure in engineering.

This is designed to do this and it will do this for the life of the truck with no issue.
