think of the stabilizing jacks as four legs of a wobbly chair where the legs are not tied together.
In order to add more stability you will need to form a triangle support system to keep the legs (stabilizer) from wobbling. JT strong arms, steadyfast system or similar is needed. I use the steadyfast, adds a great deal of stability. It does NOT eliminate any movement, just reduces the racking movement. JT strong arm acts in a similar fashion.
Next remember the trailer is supported in the middle by air shocks, your tires. they are going to act as a spring. you can eliminate some of the rocking with a chock between the tires, but you still have some up and down compression you can't get rid of.
now , the longer the trailer, the harder it is to minimize motion.
yup, our trailer still has some movement, but over time you learn to live with it and not let it bother you.
