2.) You should be able to find a bathroom scale that goes to 280 or 300
for
not much money. Counterweight the aft end of the trailer with known
weight
such that you're in the usable range of your scale, then calculate the net
effect on the tongue weight of the removal of the counterweight, based on
tentative wheel position.


That might work. Lets see.... I could put a known weight, say me, on the
end.
Just have to recalculate how that effects the tongue for each proposed wheel
position.
