If your using screw jacks the won't stop side to side movement.
NOT TRUE AT ALL and the key is putting enough force on the frame from the screw jacks and to do that you CANNOT use the screw mechanism on the jack itself you have to use the tongue jack. With around 200 to 500lbs of force on the screw jack it acts much like a solid cinder block with not movement in any plane or direction. Lawrosa has described to a "T" what is IMO the very best solution you can get. You might need to adjust the actual placement in the distance in back and in front of the axles a little and as he indicated if you have a very long trailer with a living space in the rear it might require two additional screw jacks in the rear to achieve that rock solid stability.
Lawrosa has described what I have been preaching on this trailer stability issue for over 4 or 5 years.
