Ralph S. posted a photo of his truck and preferred truck gun. It is an MP5SD in a gun rack. To assuage the fears of some, no he does not leave this in his truck unattended. It is a ballsy move to drive around with a suppressed window on display in your truck rear window. And even though it can draw unwanted attention, it does look cool. Do you drive around with a gun in a gun rack in the back of your truck?
