They are not very good criminals if they don't stick their hands under the seat to check for a handgun or anything else. This is the vehicle equivalent of hiding cash in your sock drawer, it's he first place thieves look.My pickups 5 or so times I can remember. Where they broke a window.
And hey they look for guns. Keep them hidden and locked up. My brother has been robbed at gunpoint before, its not cool.
Only thing they ever got was a drill but I was at a jobsite. I hide or remove everything if possible.
