Update on the original thread, well I had hoped that the La Crosse WS2010-15 would work as a replacement, but.... I was not able to get the replacement to spool up properly initiating the awn retraction cycle. After putting about 400 miles on the road hoping that the unit would spin it just never did. I have already gone to Girard for a replacement $142.00 the new units do have a replaceable cup system the older unit that we had. I was told by the tech at Girard that you could not replace jut the cups this unit has the black upright.
