I keep a CB in everything that might pull a trailer for long-distance trips. Pretty much only used when there's an accident or other road blockage to get a handle on which lane I want to be in to get through the fastest (or the detours the big trucks are taking). I'll usually turn up the squelch & only dial it down when something is happening on the road. Have used a few times to let big trucks know they're dragging chains, have trailer brakes burning up or overheated bearings, torn tarps, etc. Woke up a few as well when they started drifting.
Seems a lot of truckers do the same thing since there's times that it's almost impossible to raise anyone. Between cheap, available radar/laser detectors & cell phone apps that show speed traps, the bear reports are minimal compared to the seventies. I don’t miss the ratchet jaws from those days.
