I've got the 6-way leveler and scissor jacks at the extreme rear and movement is still felt. The only thing that will work to neutralize feeling movement is to get your tires off the ground.
Class A diesel pushers reduce movement to nothing by having airbags. When air is dumped from the bags they've essentially disconnected the wheels from the chassis and the jacks lift and level the chassis. Some of the heavier, larger Class A's don't use stabilizer jacks. Instead they use the airbags to level the rig. But these things are so dang heavy, in the 50,000+ pound range that the average person doesn't weigh enough to disturb things.
Class A gassers still have springs but weigh much more than our trailers, which helps reduce the movement.
Most Class C's have no leveling system at all so the motion is felt.
Airbags instead of springs on our trailers.
