Six-point leveling system -- reduce rocking

We bought our new DRV in October which is equipped with a 6 point leveling system which I admit I am still learning hoe to use it. The systems legs are installed with a 5/3 degree splay outward at the bottom to help stabilize the coach. As mentioned by others, I placed a stack of leveling blocks under each jack to shorten the throw and help minimize the movement felt inside. We still had some unwanted movement inside so I placed screw jacks under the factory installed hitch at the rear of the coach and used our king pin tripod on the front. Finally a rock solid coach with no movement. Still thinking about installing JT Strong arms however.
