does hitch weight of bumper-pull TH reduce when loaded?

It took me a while to notice why I couldn't cut my toy hauler as sharply as the same length travel trailer. After blaming my inability to negotiate tight maneuvers, I realized that the distance between my hitch and axles made the trailer feel longer than it was.

My toy hauler had a big generator and multiple holding tanks forward of the axles - This is what makes the tongue so heavy compared to travel trailers that are more balanced front to rear (especially the Euro models).
