A couple of recent Facebook posts by Tommy Herren got me thinking about truck and trailer security. What are the best deterrents/ alarms/ etc. that you've come across? The only thefts I've had in recent years is when I forgot to lock a sidebox at night... and I suspect it was a drug addict looking to turn tools into quick cash. Maybe having a truck like mine that isn't shiny new acts as a general deterrent in itself... but whatever it is attracts thieves' attention, what are the best methods to keep them out? BTW, Tommy, I wish you a speedy recovery of your stolen property.
