they were used on Alfas (Tiffin and a few other builders)from 2007-2008 and many of the unit owners have 'upgraded' the original system due to numerous failures of the original system. Atwood has an 'upgrade' kit that includes new jacks (that have a 'counter option' so they won't over extend), a new memory board and a new dash control. atwood charges their normal 'arm and a leg' for this upgrade but since these year's Alfas don't have a hydraulic system, it is really the only reasonable solution. Since Atwood requires ALL 'upgrade' systems to buy new jacks, there are several Alfa owners who have perfectly good jacks from the old system. suggest you go on the Yahoo Groups for Alfa and post a message that you are looking for the 10K jack. You might also contact Charlies Service in Sunset Utah or Alfateers in FonTana CA to see if they have any 'take off's available.
