Our new trailer came with an Atwood 3000 Premier and it ins't long for this world. It's very noisy and skips or slips the gear sometimes.
The last TT we had was equipped with a Barker 3500. I beat the krap out of that jack. I never lubed it and often lifted the back of my truck with it because the hitch would stick. After 13 years of this abuse it still worked like new when I traded the trailer.
I should also note that I bought a cover for the Barker directly from the company. After ten years the cover was worn out by the sun and rain. When I called to purchase another, they looked me up and simply sent another one for free. Great customer service there!
When the new Atwood dies, I will replace it with a Barker.
