Even hinting that you are introducing guns into the conflict can cause you serious problems. It is called "brandishing" (automatic revocation of your concealed carry license among other things) and if this ever does precipitate into violence you could end up being the one in jail. Nothing brings the cops faster than "man with a gun" calls.
Remember your "crazy" neighbor may have a gun too.
If your neighbor is making you think this hard about getting even he already won the war. He can just sit back and watch you stew in your own juice, laughing his ass off. If it does escalate into this "blow up his stuff with a megger" stage he might just burn your truck and put you out of business for a while.
