VEHICLE DESCRIPTION: 5TH WHEEL TRAILERS EQUIPPED WITH KITCHEN SLIDE-OUTS. THE PLUMBING THAT SUPPLIES LIQUID PROPANE (LP) GAS TO THE REFRIGERATOR CONSISTS OF A FLEXIBLE LP HOSE CONNECTED TO A COPPER FITTING THAT CONNECTS TO A COPPER TUBE THAT THEN RUNS TO THE REFRIGERATOR. THE COPPER FITTING IS FASTENED TO THE SLIDE-OUT ROOM WALL WITH CLAMPS TO PROHIBIT MOVEMENT OF THE COPPER LINE AND INSURE THAT AS THE SLIDE-OUT ROOM IS EXTENDED AND RETRACTED, THE FLEXIBLE GAS LINE MOVES AND NOT THE COPPER LINE. THE CLAMPS INTENDED TO HOLE THE COPPER LINE IN PLACE HAVE NOT BEEN INSTALLED CAUSING THE COPPER GAS LINE TO FLEX WITH SLIDE-OUT ROOM MOVEMENT.
