I found some time to change things around....see what you think here.
Ball height and hitch height are about 24''
The hitch has 7 washers installed...4 seem to be stock, 3 were added by me. I didn't add any since the last time.
Front end raised just under 1/4''
Back end dipped about 1.5''
6 links.

I guess the numbers are about the same. The trailer is just a tad down in the nose...much less than last time.
Do the bars look OK? They aren't parallel to the frame. Should I try and go to 5 links? Would that make a significant enough difference to the back end?
Thanks! I'm starting to feel better about my set up.
