I think a lot of how people perceive movement and what they do to reduce it depends a lot on the length of the TT, it's weight, axle ratings (spring strength) and the frame design. There are some frames on ultra-lites now that flex a lot vertically and they need to be firmly planted to the ground front and rear. (I know because we've seen it firsthand.)

Totally agree.
In our case it was the old 4000# with the single 3500# Torflex axle that was unstable. Our new 7500# Outdoors RV Timber Ridge with the twin 5200# axles (with shock absorbers) is like a rock.
At first I thought it was the Lippert electric stab jacks, but then noticed it was almost as stable with no support at all.
