So do I. Mainly because I work for the dept of an Insurance company that covers big rigs.
What are your reasons?
The dumb unemployed rednecks that live next to me have them, and at 7:30 or earlier every morning they fire them up. My bedroom is the closest to their house, so every fucking morning they fire those trucks up and let them idle for almost half a fucking hour it sounds like I live next to a railroad track.
