Channel 19 is generally accepted as the truckers channel, the one to monitor/use if you want to keep up with the conditions around you. The truckers don't miss much. When we travel solo we use it . It is often a busy channel and can get a bit vulgar at times. It is also good if something is amiss with your trailer, the truckers will usually let you know.
When traveling with friends we use 14. Doesn't interfere with the professional drivers and we enjoy chatting back and forth. And it is invaluable for communicating road info.
You can always just turn it off.
