If you look closely you will notice that the axles are 2/3 the way back from the front (IE tongue)..
If you place 100 lbs on the rear bumper your will remove 1/3 of that weight from the tongue or roughly about 33 lbs..
That puts the axles' midpoint at 17.8/28.5 = 62% of overall length.
If the TT had a single axle at 17.8',
100# added at the rear would cause about 100*0.38/0.62 = 61# to be removed at the ball.
In your example where "the axles are 2/3 the way back from the front" (and if the trailer is single axle),
100# added at the rear would cause about 100*0.333/0.666 = 50# to be removed at the ball.
In order to remove a load of 33#, the axles would have to be 3/4 of the way back -- not 2/3.
