Dear Sirs, I have a 1992 Holiday Rambler RV that is needing a TS-30 Transfer Switch. I need to purchase the entire unit but cannot seem to find a unit like the one on the RV. The Transfer Switch that is currently in the unit is from your company Elkhart, Indiana. It just says TS-30 then the year it was manufactured and that is it. If I can purchase a new unit from you please let me know and I will surely get one. I would like to stick to the original parts that need to be in the RV. Thank You very very much for your time. Karen Dunn
