Ditto, did the same...I thought ours worked fairly well. That being said, I'd not buy a brand new one. We found one on craigs list for $50 that had only been used a few times.
If you have a Trail-Air or similar suspension on your king pin like we do, it will actually make things worse. Go with the strong arms on you jacks and rear stabilizers, better bang for the buck and self storing.
I respectfully disagree......and agree.
I have a tripod and the Trail-Air pin box. It does not make things worse, it does help.
But I agree that the J.T. type stabilizers would be a better choice.
Peace
