Google 'Jimmy Jammers'. They stop the lock from being able to be punched in, and protect the rods so thieves can't access them through the bottom of the plastic door handle bit.
With the loads I haul and driving an older generation Ford Diesel I needed extra protection for my truck. I installed a Ultra 2-WAY FM/FM XR LCD REMOTE W/ PAGER AND ALARM. This has worked great for me and with the pager mode if anyone opens a door without the remote it not only sets off my alarm but notifies me via remote (thats always on my night stand) that somethings up! I also installed another bypass which completely disables the computer so even if the thiefs are super thiefs they won't be able to move my truck.
I believe they follow these websites and gain alot of information so be careful what you post at times.
Theft is a business with high profit. The cost involved with an honest man trying to get through life is becoming tough. And it's going to get worse. Many people are buying parts off of many different web sites to save $$$ and no questions asked. We all know how this works and it's not going away any time soon. So protect yourself where you can and hope for the best. Remember, it only takes one person wanting it more than you :d
I beleive in clubs also! Ive had two different trucks broken into, but I still owned them the next day! I'm thinking the only reason being is that club! They stole nothing, all I got in my trucks is a cowboy hat, some caps, and CD's. Them dam punks don't want that stuff so they throw it around and leave it! Although if I had a security system I woulda woke up and coulda shot at the bastards!
