Some people just think the factory alarm will protect their belongings and it doesn't.
neither does your fancy-shamnzy aftermarket alarm.............
Tell me how an aftermarket alarm is going to "better protect your belongings" than the factory alarm. Does it automatically pepper spray the dude and then tazer him when he jimmies your door open or something?
You think some super-dooper loud siren is going to scare off some punk after he smashes your window, grabs all your stuff in less than a minute, and then takes off? When is the last time anyone even paid attention (or called the police) to a car alarm that was going off, honestly?
Expensive alarms are for suckers, IMO. They dont protect your crap any better than the factory alarm. If a theif wants something in your truck, hes gonna get it.
Really the only anti-theft device that I think is worth doing is a custom (IE, not something you buy off the shelf that every theif knows the ins-and-outs of) ignition/starter kill switch. But even then, thats not going to stop a flat bed from taking your truck. Luckily im never really in a situation where I have to leave my truck in a sketchy area, but If I do, Ill pull some fuses, unplug one of the ECM connectors, or just take the whole ECM with me....
The best anti-theft system in the world is a good insurance policy...
I dont mean to sound like an ass, but......its the truth.
