definitly flipping your axle below the springs will help. Do you have a mounted ball in your bed for your gooseneck or is it a king pin and receiver. you may find some different adapters for the height of the balled gooseneck. i'll check with my buddy back home and see what he did to his horse trailer when he lifted his truck. i think it was a combiation of flipping axle and receiver adjustments. i'll get back to you.
