How are you guys immobilizing your vehicles in an effort to deter thieves? We lock up the Superclamps and I have a 3/8" diameter cable that we snake through the sleds and lock to the deck with a large hardened steel security padlock. I think this takes care of the sleds, but I'm wondering what the best way is to immobilize a 2009 Silverado 2500HD. Pulling fuses? If so, are there any in particular that are best to pull? Has anyone installed a hidden switch to cut power to a critical circuit? I realize its kind of a sensitive thing to be posting secrets. Maybe a PM or email is the best way to discuss any specific ideas.
