Please dont take this the wrong way. But if your not sure whether your stripping the threads, wrong sized socket, or your ratchet isn't working, maybe you should get someone to help?
Run the truck until it gets to operating temp, shut it off and give it a try. The heat will help expand the threads around the plug. Also, put the socket on the plug and smack the socket with a hammer not tap. The impact helps loosen it up, not help the oil penetrate.
Your using a spark plug socket right?
