They remove all bounce from the frame and suspension. Lower the front place two at the rear, raise the front just past level and place the two in the front then lower the front onto the jack stands. Place one under the frame on each side at each corner. Rock solid.
Do this, plus chock the tires front & back on both sides.
Stabilizer jacks are not adequate to stop the movement. I'm like you, any movement in the trailer drives me crazy when I'm trying to sleep.
