Will Stable Loads help with o/loads already engaged

I would think that lowering the truck in the back would transfer some weight off of the front end so if you can prevent some of that lowering or squat it would keep more weight on front end.
By looking at some of the weight slips folks have posted you can see that adding a camper has lightened the front end load.
I know from overloading some trucks in the past I have gotten some really light steering.
