TWO RV MANUFACTURES, NAVISTAR AND KEYSTONE, HAVE DONE VOLUNTARY RECALLS UNDER CAMPAIGN NUMBERS 12V060000 AND 11V577000. MY UNIT IS NOT ON THE RECALL BECAUSE NAVISTAR PURCHASED MONACO CORPORATION UNDER CHAPTER 7 AND ASSUMED NO LIABILITY FOR MOTORHOMES BUILD UNDER THE MONACO CORPORATION NAME. THE NHTSA NEEDS TO START AN INVESTIGATION ON THIS TRANSFER SWITCH. IT HAS BEEN REPORTED BY NUMEROUS TRAILER TRAILER, FIFTH WHEEL, AND MOTORHOMES OWNERS THAT THESE UNITS HAVE GOTTEN HOT TO THE POINT OF BURNING WIRES AND CAUSING FIRES. ACCORDING TO SOURCES SOME OF THE INTERNAL PARTS OF SOME UNITS MAY HAVE BEEN MADE FROM INFERIOR MATERIALS WHICH OVER TIME DEGRADE AND INCREASE RISK OF OVER HEAT. *TR
