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

This is a very simple topic. It is amazing the wizards on this site don't understand it. More frame flex = poorer steering geometry. The trucks will steer themselves on a cambered road when loaded. The heavier the load, the more flex, the more self-steering..........
The trucks with the stiffer frames will force the suspension to move. The suspension will control wheel alignment within the limits of the design. The reason the OTR trucks flex the frame is because the suspension is stronger than the frame. This is not the case in light duty trucks.
The goal is the stiffer frame and better steering geometry. It will never be perfect.

How refreshing; someone that knows something about suspension and frames on this site. :)
Anytime you have the frame work as a suspension component that is bad news.
Kenneth, just in case you missed the link earlier.
