people have different 'feelings' about amounts of RV movement, as some are more sensitive to it than others, and some have differing RVs that will have different profiles that lean more toward 'movement' no matter what you try to do about it, outside of sitting the whole frame down on a foundation, at least.
the 'frame' of the RV is the key place to be aware of when it comes to 'how' to minimize movement. Even though you might have jacks or stabilizers on the far front and far rear ends of the frame rails, you can try to also put similar stabilizers every 10-12' along the whole of the rv, if space allows it. Now, your slides and how they are configured are going to come into play, too, as if this includes seating, every time you 'sit' your weight down you are asking a lot of the RV to not move slightly when that happens. You can also deploy slide jacks/stabilizers, which we do on our camper, since that's where both boys 'plop down' to sit at their computers all day!
