2010 FOREST RIVER SANDPIPER Electrical System Problems

WHILE ON OUR 1ST CAMPING TRIP, WE SMELLED SOMETHING ELECTRICAL BURNING. UPON INVESTIGATION, I FOUND THE 50AMP ELECTRICAL LAND LINE BURNED UP AT THE PLUG. WE CUT OUR TRIP SHORT AND IMMEDIATELY CAME HOME. I ATTEMPTED TO HAVE FOREST RIVER AUTHORIZE A REPAIR LOCALLY, BUT THEY WANTED ME TO RETURN TO THE POINT OF PURCHASE (5 HOURS AWAY). WE HAD ANOTHER TRIP PLANNED THE FOLLOWING WEEK SO I LOOKED AT THE PROBLEM. THE 50 AMP SOCKET HOUSING WAS INSTALLED 180 DEGREES REVERSE (EVEN THOUGH IT SHOULDN'T BE POSSIBLE BECAUSE OF A MOLDED KEYWAY IN THE HOUSING). IN ORDER TO ASSEMBLE THE SOCKET, AFTER WIRING IT, IN THAT MANNER, IT HAD TO BE FORCED TOGETHER. AS A RESULT THE LOCKDOWN FOR THE WIRING CAUSED IT TO PULL AWAY FROM THE SET SCREW AND GROUND TO THE NEUTRAL WIRE. THIS CAUSED A SMALL FIRE WHICH BURNED THROUGH THE HOUSING AND LAND LINE...
