Trying to understand payload

I just finished watching this You Tube video where they guy has the same WE that I have in storage. I recognize it now. He was showing how to do it. I'll read more but it seems easier to understand now. If I have this right a weight distributor should raise up the hitch and back end of the truck just enough to redistribute some of the weight to the front and some to the back. If properly done breaking and control should be greatly improved over not doing it at all.


I am feeling so much better now. What next should I be considering?
