If you increase the tongue length, you will increase the tongue weight
by exactly the amount of weight of the added tongue material. Leverage
has nothing to do with the tongue weight. If you move the axles
backward you will increase the tongue weight, forward will decrease the
tongue weight. Tom.

I disagree. A trailer is just a class 2 lever. If the distance
between
the wheels & the ball were doubled, the tongue weight would be cut in
half.

I'm sorry, I'm just not following this train of thought. Let's forget a
trailer for a moment. Take an object that is long, like a 10' piece of pipe
for instance, and lay it on the ground to simulate the trailer. Support the
pipe at say 60% of its length with another object, say like a 2x2, to
simulate the axle. The longer end of the pipe is the tongue end; weigh the
very end of the long end. Now move your 2x2 so that the tongue end is 90%
of the pipe's length. Now weigh the long end. Won't the weight at the end
of the long end be greater that it was when the 2x2 was at only 60% of the
length?
