Bro that is my worst fear, having my car broken into. Somenights Ill stay up late playing counter strike or what not and before I go to bed look out my window and I always fear someone is walking to my truck. But I DO have an alarm and without it I dont know if I would have any peace of mind. *Viper 2 way LCD system with 4 exterior alarms, 1 interior, hood lock and back up battery*

I would invest in an alarm if I was you if you are paranoid now. Most shops around here will install a basic alarm for 90$ or so that way if they do try something, you will hear it
