The gas line thing is quite vague it can not be used as a ground but maybe bonded to a ground. I'm not sure if there is a need in an RV as the tank side is non conductive. Any way you need a frame ground the piece you have is a broken ground lug it most likely rotted off. Just buy a new one and go some where else and find some #10 or 12 wire the #6 you have will be a right pain in the back side to install trust me you'll never want to look at a wire again after fighting it, fine in a big box but not in a small space. There should be a lug on the side of your converter the ground wire needs to go to that too if there is not a lug install one and bond it to your frame ground lug. Your new box should have a threaded hole all ready in it sheet metal screws are not allowed. See if you can find some bonding grease while your at the store and apply it to the frame lug the surface needs to shine really bright and stainless nuts and bolts would not hurt.
