I saw plenty of cars with tracking devices and advanced alarm systems stolen and never recovered in Miami. They would put them in a container and off to a foreign country. Lojack did a search in south America and found a bunch of the stolen vehicles. The government of that foreign country would not let the cars be shipped back. Of course they needed a nice ride too...
If you back your truck in and use your hand brake it makes it harder, but not impossible, for a flat bed to get it. I also use to use a thing called a cap. It covers the steering wheel with a plate and a rod making the car hard to steer and protected the air bag. Not impossible to disable but more of a pain factor.
