2009 KEYSTONE LAREDO TRAVEL TRAILER. AS I WAS BACKING UP MY TRAILER TO PARK IT, MY STABILIZING CHAINS PINCHED THE WIRING FOR MY BREAKAWAY BRAKES WHICH IS MOUNTED ON THE FRAME. A FIRE RESULTED AND BURNED THE WIRING. I HAD TO PUT THE FIRE OUT TO AVOID MORE DAMAGE AS IT WAS VERY CLOSE TO THE 2 PROPANE TANKS. I HAD TO REPLACE THE WIRING AND RUN IT UP UNDER THE FRAME TO AVOID THIS FROM HAPPENING AGAIN. THE POSITIONING OF THE WIRES MAKES IT VERY SUBJECTIVE TO FURTHER INCIDENCES. *TR
