sales hype. If a rigid frame was better Class 8 road tractors would use them.

If a class 8 truck was designed to go off the pavement then they would make them more rigid and AWD.

Ever see a logging truck? No AWD just chained up wheels and locked diffs,pulling god knows how much wieght with mud up to the frame .If the tires find 'bottom' they move.
Plain jane kenworth or petes just like you see on I75

No they are not Plain Jane just like what you see on I75. Their frames get doubled. I'm also not saying that rigid is the only way to go in all situations. Class 8 truck are designed completely different. If you notice, everything from the cab to the hood to the exhaust is attached to the frame in a way that it allows the frame to flex under extreme torque of the engine. The cab on your truck only attaches to the frame at the front with hinges and the hood is the same way.

I'm also not saying that the Ford frame is not strong, I'm saying it is not strong enough to keep all the parts working. Their frame works fine on a truck that you don't have to open the tail gate on but they either need to make a more rigid frame or more rigid bed.
