Without moving the axle forward, I do not understand how lengthening the pole would reduce TW. Adding pole will only add TW

Think about it a little longer. Remember Archimedes? This involves lever arm and fulcrum. Yes, a longer trailer tongue length effectively reduces the force applied downward at the hitch ball, all other things being held constant.

Would you rather pull a nail with a very short crowbar, or a long crowbar? The nail will come out much easier with the long crowbar.
