Flat spots on front axle tires

Thanks for the responses. When I say nose high I would have to lower the front of the rig 2-3 inches for the bubble to be in the middle of a level. By the highest position on spring hangers I mean the rig is highest at that setting. I am not sure maneuver Jack rig is, but the B&W hitch does not slide. I feel that I need the 7 inch clearance because we boondock camp a lot and need that much.
