Two more scams.
A truck driver who drives the same type of truck you do "locks themselves" out of their truck. They ask you if you could try to unlock their door with your key. If you are able to,they watch to see if you get out of your truck. When you do,they unlock your door,and rob you blind.
A drifter asks to use your CB to see if another driver can give them a ride. They go in your truck,and give a sly glance at what you have inside. When you step out of your truck,they break into it,and rob you.
