I'd say you are on the right track as you really want the fifth wheel pin weight to be right at 20 percent of the total trailer weight. Which for your trailer that weighs 10,500 lbs that would be right at 2,100 lbs.

So what I recommend you do is follow the picture I attached to determine how far exactly to move the axles. I'd do it for you but I don't know the distance from the tongue to the center hanger's center.

I also attached a help article on how this is done as well.
