I am really surprised this didn't kick up

I watch the "how cars are made" stuff on MT. Intresting. Everything from every foreign exotic to even a Chevy Camaro!!!! Makse a difference if making a $200,000 Porche or a $30,000 Camaro!
I still say domestic makers of run of the mill cars, back in the 60's and beyond, do anything to save a penny and make another buck.

I wonder why pickups an big trucks still use a full frame and not a unibody?
Load carrying capabilities and towing. And the trucks are designed to allow for some frame twist.
