Looks to me like you could unhook on level pad, then level RV. Then measure from the ground to the bottom of the RV near the pin box. Then measure from the ground to the bed rails on your big 4x4. The RV should be about 6 inches higher. If not, add risers to your RV to bring it into the 6 inch clearance parameter. Then backing under the RV, check if you really do need to adjust your pin box.
