lodge a live smoke grenade under your hood. When they open it, the spoon flies and the smoke starts. If you can get a CS grenade, thats even better. 220V to the hood latch on a 30A breaker is more than enough to scare someone away, would be pretty EZ as the entire truck is on the ground leg and the 2 110V hots can be sitting under there where the latch is. Bring some marshmallows. A nail board under some leaves by the front bumper might piss someone off. Shotgun shells rigged to a cocked mousetrap about nard height behind your grill, they open the hood, trip wire pulls bait arm and they say good buy to any future painless head call.
>> If you want to be known as "Chemical Ali" put industrial bleach (not diluted household stuff) and good grade ammonia in seperate small plastic water bottles tied together around an M80 in some sort of open ended containment device like an old battery case. Get a birthday popper from the toy store and pull the little ladyfinger out of it. It has a pull string on it that ignites the tiny charge when its pulled out of the ladyfinger. Stuff the entire igniter into the M80 and tie the pull string to the hood of the truck with about 18 inches of slack. When the hood comes up, the charge goes off, the M80 Breaks the bottles and the binary chemical weapon reacts creating one of 3 things depending on the ratios:
>Nitrogen Trichloride (NCl3) which is a toxic substance that's also highly explosive.
>Hydrazine (N2H4) which is a component of Rocket fuel, also explosive
>Chlorine Gas (Cl2) which tears into your nasal passages, trachea, and lungs, causing massive cellular damage!
