Your neighbor is obviously irritated by your truck. Likely because it's loud. Hot Rods in general sound like they are speeding when in park.
There is probably something else going on at home that is causing him to take things out on you.
Some people you just can't reason with but I'd try killing him with kindness first. If that doesn't work then be ready for a visit from your local PD.
Keep a camera with you and if he gets out of line start the video rolling. He will then be the one on the bad side of the law.
A cold beer and a ride in the truck might break the ice too. Preferably not at the same time though.
