In my truck (see sig) the CB is mounted to the left of the steering column, and the all band/all mode Yaesu amateur radio is mounted to the right of the steering column, covering the ashtray.
I am currently using magnetic mount antennas on the top of the cab.
There has been an on-going move to have RVers use CB Channel 13, but it hasn't gained much acceptance. Most mobiles use Channel 19 along with the truckers. the problem there is that the truckers can sometimes (often) be guilty of, shall we say, "colorful" language. On second thought, let's just tell it like it is: Crude and profane, often times simply obscene.
