Sounds like replacement under warranty is in order. I see the 2016s now have Atwood Jacks. I had the older design Barker Superjack then damaged it. Got a replacement Superjack from Barker. Noticed some issues with it and sent it back under the Barker warranty. A different one was returned, seemed to work OK at first but now makes a terrible rattling noise on the down stroke in certain positions. Normal on jacking up. I'm ready to give up on Barker.
