I have the 3000 on my Bambi and the up switch quit. The theory from Barker support was that water got into the switch and probably shorted out the up component. They were very prompt in sending me the parts. Excellent customer service in that I was using the part that was provided by Airstream
to lift the trailer. I forgot to take it off and was lowering the trailer. The handle flew around and broke the top which holds the leveler/cap. They were gracious enough to send the whole tope to replace my error. That is good customer relations. Of course, one could say... for lack of a nail, a horse shoe was lost.......
They also sent a vinyl cover for the whole mechanism to keep the water out,
made me wonder why it was not included from the get go... Airstream, dealer, or Barker?
