The slides are made not to need the supports. Also, if you have supports under the slide and you have a tire go flat, it can be very expensive as the weight for that side is now transferred to the slide and usually causes a good amount of damage. To alleviate some of the movement, try putting blocks under the hydraulic jacks so they don't extend so far, using X-chocks and some even use a pin box tripod to get all of the shake out. However, if the unit is still supported by some weight on the suspension, it will still move some.
