Ideas for a alarm system
There is no point in having an alarm which wails on the outside of the car. Annoys neighbours, and anyone in the shopping centre when your alarm goes off and is next to useless because everyone just ignores it.
Get as many piezo alarms as possible and stuff them on the INSIDE of your truck and hook them to the alarm. No-one will be able to stay inside your truck with them all going off.
Things I've heard other people do though include blinking LED lights on the dash (not necessarily hooked up to anything), "the club", and in some extreme cases, shatter proof glass...
Personally I don't think its worth it, just keep your truck locked, and keep an eye on it...
