weight distribution sway control suggestion

I have the Blue Ox Sway Pro and after I finally got it dialed in correctly must admit I really like it. My hitch weight is about 810 lbs. First time out with it I had to much weight distributed to the front wheels of the F350 and the ride was harsh. 2nd time out I fixed the weight distribution after carefully measuring everything and setting it up correctly instead of the sloppy mess the dealer had it set up but I was getting some sway under modeate to heavy braking. Finally figured I had to much weight in the back of the Travel traler so moved alot of stuff to the front bedroom on the trailer for travel and now the excessive sway under moderate braking is gone although you still get some under extremly heavy braking.
