WE PURCHASED THE 2006 SUNNYBROOK TITAN FROM BUDDY GREGG BACK ON JULY 7, 2017. THE SECOND WEEKEND OF USING THE UNIT STARTED WITH THE FAILURE OF THE IOTA ITS-50R TRANSFER SWITCH. WIRE AND INSULATION BURNED, THE TERMINAL LUGS MELTED/FUSED, AND THE PLASTIC COVER STARTED TO MELT. THE RV WAS STATIONARY. WE WERE ABLE TO GET A TECHNICIAN TO RESPOND SATURDAY AFTERNOON AFTER SALESMAN TOLD ME THE SERVICE DEPARTMENT AT BUDDY GREGG WAS NOT OPEN ON SATURDAY. AFTER REPLACING THE ATS, THE TECH FOUND THE HEATING ELEMENT OF THE REFRIGERATOR WAS FRIED AS WELL AS THE CONVECTION MICROWAVE. THE TECH WAS ABLE TO REPLACE THE HEATING ELEMENT AND REPAIR THE REFRIGERATOR. A FEW HOURS AFTER THE TECH LEFT, THE REFRIGERATOR BOARD APPEARED TO FAIL, THE 12V LIGHTS DIMMED, AND THE PROPANE ALARM WAS TRIPPED. THE LIGHT PATTERN ON THE ALARM INDICATED A POWER FAILURE. WE CONTACTED THE TECH AND DETERMINED THE CONVERTER/INVERTER WAS EVIDENTLY IRREPARABLY DAMAGED BY THE FAILURE IOTA TRANSFER SWITCH. WE NOW HAVE TO HAVE THIS REPLACED. RESEARCH REVEALS THE IOTA ITS-50R TRANSFER SWITCH HAD SEVERAL RECALLS ISSUED FOR IT SEVERAL YEARS AGO. ONE INCLUDED THE TIGHTENING OF TERMINAL LUGS TO 45 POUNDS AND ONE ISSUED LATER FOR TOTAL REPLACEMENT OF THE UNIT. OBVIOUSLY THE PREVIOUS OWNERS OF THIS RV EITHER DID NOT EVER GET A RECALL NOTICE, OR JUST OPTED NOT TO HAVE THE UNIT REPLACED. ALTHOUGH WE UNDERSTAND THIS RV WAS USED WHEN WE PURCHASED IT AND WAS ASSURED IT HAD PASSED THROUGH SOME TYPE OF INSPECTION BY
