I had a bipod kingpin support back when ... does one of your legs have basically an old ratcheting bumper jack head off the 70's era cars and a chain between the two feet? If so and you want to try it, adjust the spacing on the legs in or out to contact the king pin. Secure it to the king pin with the supplied ubolt gizmo. Hook the chains together as tight as possible down by the feet. Jack the jack head up just like you were jacking up the old 70's car till you fell pretty good resistance ... you're done. I really wasn't too impressed with it's benefits, so I didn't use it long. JT'stabilizers or it's knock off competition are way better ... unless you have an extra 5 grand laying around to play with the big boys and install a level up ...
