Ram dually vs Ford dually Frame Flex Comparison
Interesting vid. Should they be strong enough to bend, or is a rigid frame better? Frame Flex Vid

Did they beef up the F150 frame or did they just reduce the overall weight by using the aluminum body thus raising payload cap. and then retain the previous frame design?
They did both...
The steel may physically be thinner on the frame, but they changed alloys to achieve even greater strength and torsional stiffness. They went to some form of UHSS (ultra High Strength Steel), which is the stuff commonly used for A/B/C pillars on unibody cars for greater roll protection and on certain cross members where the engineers do not want deformation in a crash. The aluminum was thicker on a 2015 truck than the steel the body of my 2010 F-150. The 2015 truck was sitting behind the velvet rope at a car show, but I figure I'd poke at the panels when the spokesman wasn't looking :). Much stiffer feeling, but will still dent if it gets hit hard enough. Still not nearly the solidness of a car from the 60's/70's for fender panels. But those days are long gone.
