If you compare the wheels on the picture, the Chevy RR wheel is about 16" above the ground, Ford's about 8". That where the suspension travel shows.
Stiff A/S bar would make the travel smaller so everything needs to be in balance.
You gain in one aspect, loose on the other.

You could weld the Ford axles to the frame then the tires on the Ford and Chevrolet would be the same distance from the ground. With a welded axle to the frame I would say you have no suspension travel.

You have confused suspension travel with frame flex.

Sounds like you are saying Ford's frame flexed 8" more than Chevy's frame.
It ain't so.

I think there is good reason you don't see steel ladders at Home Depot.
All those aluminium ladders flex on the jobs every day for even 40 years.
I think one of my ladders is 60 years old.

There are several reasons . It would take 2 men and a boy to handle a 40' steel extension ladder , and another is rust . Each product has it's place and are not always equally interchangeable .

The reason for truck frame is cost and technology.
It wasn't till last generation that technology come with easy aluminium welding.
Now all upscale semitrailers are aluminium.
So are all flatbeds.

There is a reason that truck frames are usually made of steel as well. :)

It all comes to engineering.
When steel can be hardened to several levels, aluminium can have mix that will increase it strength by multi-fold.
Our Mercedes has rear axle frame cast/welded from aluminium.

If you design for it the extra twist is not a bad thing.....it keeps your wheels planted with a more equal weight per wheel for traction purposes.....but again, you have to design for it.....this also appears to be unloaded, so I'm unsure of the value of the comparison.

That is what competition doesn't want to see.
I noticed on the picture that Ford suspension has about twice the travel as competitor.
That plays big role in offroading.

With the Chevrolet VS Ford where do you get the suspension has twice as much travel?

If you measure from the top of the bed rail to the bottom of the tire on the left and right side of both trucks the measurements are almost the same. Thus about the same suspension travel.

The only difference I see is how much the frame has flexed.

This was also true with the Ram vs the Ford.
