When my friends truck was stolen, they rolled it down the hill and hotwired it from there.
My switchbox has a valet key on the side so you can lock it out and the box came with a pancake function for alarm output. So if the alarm goes of, the dump valves open. You "could" drive my truck dumped, but it's tough. If I ever lay it out, then that wouldn't be an option.
I am going with a paging alarm with auto locks. My goal is to keep my truck as ghetto as possible so there is little interest anyway
