I live in an area that I can still leave my truck unlocked overnight. I'll be making a trip to SoCal on the 28th. I have little faith in the after market alarm systems. With the high occurance of theft there I'm looking for ideas on making my truck non-operational. I'll start with the fuel line shut-off valve, I'm just curious if any of you have any other systems you use. My truck will be parked on the street during my visit and I don't want to worry about getting home. Any ideas or thoughts???????? Merry Christmas, Mike
