Level trailer

This is almost entirely incorrect, as an extremely nose high trailer compared to and extremely nose low trailer "may" shift a very small amount of the tongue weight fore or aft by virtue of whatever weight is directly above the pivot point (axles) and the change in vertical component of that force (weight) by whatever angle it's at (couple degrees) from plumb or level.

Extreme being a couple/few degrees. Your example is with a single axle trailer that doesnt behave the same as a heavier tandem trailer. Like a tow behind air compressor or small gen set. They don't have a proportionate amount of tongue weight to begin with. They're fairly balanced and actually tow like **** because they dont have enough tongue weight to begin with thats why you can stand them on the back bumper when you pick up the tongue 30-40degrees.

If said tandem axle trailer is a torsion spring trailer, your last statement is incorrect due to the 2 axles not equalizing, in which case nose high and weight on the rear axle would make the front correspondingly heavier, not lighter as the pivot is now further rearward. And with the effective center of axle further rearward, apples to apples the trailer will be more stable and tow better because there's less tail waggin the dog.
