WD and tongue weight. Please check #'s

I will let someone else do a complete analysis, but it appears that you are only achieving a little over 50% front axle load restoration. You should be able to attain 100% with your Equalizer hitch. Download the instructions or read them as posted on the forum. Good job getting some good scale weights, although it still looks like there are about 100 pounds floating around somewhere.
8,580 + 6,440 = 15,020, not the 14,900 total combined weight shown.
