Good job!
I Didn't even think about lowering it into the "straight out position" for a straight pull.
I love to play at fabracation myself, when I got my "multi mount" cradle I put some gussetts on the side and ran a few passes over the factory welds.
I am still concerned how it will perform in a side pull situation. I applaud your creativity and good luck with your mount. I have access to a very accurate load cell if you ever want to test it
