Glad you got your problem resolved.
I've been working on similar issues with ours since we bought it a year ago. Following up on what Harvard said, in my research I found that Ford targets 30% minimum for front axle loading. With our rigs having large basements, a big rear overhang, and tanks that may be aft of the rear axle, it's very easy to throw off the balance. I weighed my axles separately and found that even with relatively light loading, my rear axle didn't have all that much margin.
Just food for thought.
