Need Help Operating Atwood Levelegs System

Sounds to me like it was working as advertised. I, personally, don't like my wheels off the ground and will use 2x10s to place under them to prevent it. Anytime I use boards under the tires I will use the same number or one more under the jacks in the same position (front jacks in your case) to prevent the Levelegs from extending too far. They are prone to failure when over extended.
