When parked, I see some Class A's with blocks under there stabilizers, and others on the ground. Does the blocks stop the Motor from some motion in them? Which is the best way to park?
Some use pads to increase the footprint on the ground, to help level the MH, especially if the ground is soft. Some use pads to get increased lift, when needed. The less you extend the leveling jacks, the more stable the MH will be, as there will be less flex in the jacks themselves.
